It's now possible to use Broadcom functions to read the I/O registers of
SDIO card. The functions were copied from the BSD-licensed Broadcom Linux driver
as-is. To make it possible, a small Linux compatibility layer was introduced.
Currently the card responds with the correct version number ("magic")
when reading the corresponding address.

When it was added in r314636, AMD Thresholding was hardcoded to only
bank 4 (Northbridge) for some reason. However, even on family 10h the
MCAx_MISC register Valid/Present bits determine whether thresholding is
supported on that bank.
Expand thresholding support to monitor all monitorable banks. This
simplifies some of the logic and makes it more consistent with our Intel
CMCI support.

Modify blst_leaf_alloc to find allocations that cross the boundary between
one leaf node and the next when those two leaves descend from the same
meta node.
Update the hint field for leaves so that it represents a bound on how
large an allocation can begin in that leaf, where it currently represents
a bound on how large an allocation can be found within the boundaries of
the leaf.
The first phase of blst_leaf_alloc currently shrinks sequences of
consecutive 1-bits in mask until each has been shrunken by count-1 bits,
so that any bits remaining show where an allocation can begin, or until
all the bits have disappeared, in which case the allocation fails. This
change amends that so that the high-order bit is copied, as if, when the
last block was free, it was followed by an endless stream of free
blocks. It also amends the early stopping condition, so that the shrinking
of 1-sequences stops early when there are none, or there is only one
unbounded one remaining.
The search for the first set bit is unchanged, and the code path
thereafter is mostly unchanged unless the first set bit is in a position
that makes some of those copied sign bits matter. In that case, we look
for a next leaf, and at what blocks it can provide, to see if a
cross-boundary allocation is possible.
The hint is updated on a successful allocation that clears the last bit,
but it not updated on a failed allocation that leaves the last bit
set. So, as long as the last block is free, the hint value for the leaf is
large. As long as the last block is free, and there's a next leaf, a large
allocation can begin here, perhaps. A stricter rule than this would mean
that allocations and frees in one leaf could require hint updates to the
preceding leaf, and this change seeks to leave the freeing code
unmodified.
Define BLIST_BMAP_MASK, and use it for bit masking in blst_leaf_free and
blist_leaf_fill, as well as in blst_leaf_alloc.
Correct a panic message in blst_leaf_free.

The usbphy node for allwinner have two kind of resources, one for the
phy_ctrl and one per phy. Instead of blindy allocating resources, alloc
the phy_ctrl and pmu ones separately.
Also add a configuration struct for all different phy that hold the difference
between them (number of phys, unknow needed register write etc ...).
While here remove A83T code as upstream and FreeBSD dts don't have
nodes for USB.
This (plus 323640) re-enable OHCI on Pine64 on the bottom USB port.
The top USB port is routed to the OHCI0/EHCI0 which is by default in OTG mode.
While the phy code can handle the re-route to standard OHCI/EHCI we still need
a driver for musb to probe and configure it in host mode.
EHCI is still buggy on Pine64 (hang the board) so do not enable it for now.

Some makefiles do reachover builds.
In some cases it is convenient to list subdirs of the distribution
in SRCS.
It is not very convenient, or always even desirable to have corresponding
subdirs in .OBJDIR, so OBJS_SRCS_FILTER allows the makefile to choose.
The default value 'R' matches existing practice.
But a makefile can set OBJS_SRCS_FILTER= T (the R gets added by
bsd.init.mk) to avoid the need for subdirs in .OBJDIR

To optimize the case of ping-ponging between two buffers, the DDP code
caches the last two buffers used keeping the pages wired and page pods
stored in the NIC's RAM. If a new aio_read() request uses one of the
same buffers, then the work of holding pages, etc. can be avoided.
However, the starting virtual address of an aio buffer was not saved,
only the page count, length, and initial page offset. Thus, an
aio_read() request could match a different buffer in the address
space. (Earlier during development vm_fault_hold_quick_pages() was
always called and the vm_page_t values were compared, but that was
eventually removed without being adequately replaced.) Fix by storing
the starting virtual address and comparing that (along with other
fields) to determine if a buffer can be reused.

- The exit probe was not appropriately filtered to only the known pid so it
was firing on any random process that would exit rather the only the one
we cared about.
- The dtest script executes the tst.raise*.exe in the background from
POSIX sh without jobs control. POSIX mandates that SIGINT be set to
SIG_IGN in this case. The test executable never actually tested that
SIGINT could be caught despite trying to block and delay the signal.
So the SIGINT sent from raise() is never actually received since it
is ignored. This could be fixed by calling 'trap - INT' from dtest
before running the executable but I've opted to just use SIGUSR1
instead in these specific tests rather than adding more logic to
test that SIGINT is not ignored at startup.
These 2 issues meant that the tests would randomly work but only if a process
coincidentally exited during the test.
