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.

In theory, all data access errors mean that a member is out of sync
at most. But they were treated as more serious errors to avoid the
situation where a flaky disk gets repeatedly disconnected, re-synchronized,
reconnected and then disconnected again.
ENXIO is a special error that means that the member disk disappeared,
so it should get the same handling as the GEOM orphaning event.
There is a better chance that when the disk is reconnected, it will be
a good member again.
When ENXIO happens on a read we use the exisiting G_MIRROR_BUMP_SYNCID
mechanism which means that the mirror's syncid is increased as soon
as there is a write to the mirror. That's because no data has got out
of sync yet, but the problematic memeber is disconnected, so the future
write will make it stale.
When ENXIO happens on a write we use a new G_MIRROR_BUMP_SYNCID_NOW
mechanism which means that we update the mirror metadata as soon as
possible because the problematic memeber is already behind.

When a newborn socket moves from incomplete queue to complete
one, we need to obtain the listening socket lock after the child,
which is a wrong order. The old code did that in potentially
endless loop of mtx_trylock(). The new one does only one attempt
of mtx_trylock(), and in case of failure references listening
socket, unlocks child and locks everything in right order. In
case if listening socket shuts down during that, just bail out.

This is initially used to work around a bug in old versions of QEMU that
trigger such an exception when reading from an ID register when it should
load z zero value.
I expect this could be used with other exception types, e.g. to emulate
