Upstream DTS for A64 SoC doesn't provide a /clocks node as Linux switched
to ccu-ng
This commit adds the necessary bits to boot on pine64 with latest DTS from
upstream.
USB is not working for now and some node aren't present in the DTS (like the
PMU, Power Management Unit).
Tested on: Pine64
iflib - reset fl-ifl_fragidx to 0 on iflib_fl_bufs_free(). This caused the
panic in em/igb when adding it to a bridge device.
iflib - Handle out of order packet delivery from hardware in support of LRO
Out of order updates to rxd's is fixed in r315217. However, it is not
completely fixed. While refilling the buffers, iflib is not considering
the out of order descriptors. Hence, it is refilling sequentially.
"idx" variable in _iflib_fl_refill routine is incremented sequentially.
By doing refilling sequentially, it will override the SGEs that
are *IN USE* by other connections. Fix is to maintain a bitmap of
rx descriptors and differentiate the used one with unused one and
refill only at the unused indices. This patch also fixes a
few bugs in bnxt, related to the same feature.

Instead of using GID_FT SNS request to get list of registered FCP ports,
use GID_PT to get list of all Nx_Ports, and then use GFF_ID and/or GFT_ID
requests to find whether they are FCP and target capable.
The problem with old approach is that GID_FT does not report ports without
FC-4 type registered. In particular it was impossible to boot OS from
FreeBSD FC target using QLogic FC BIOS, since one does not register FC-4
type even on new cards and so ignored by old code as incompatible.
As a side bonus this allows initiator to skip pointless logins to other
initiators by fetching that information from SNS instead.
In case some switches do not implement GFF_ID/GFT_ID correctly, add sysctls
to disable that functionality. I handled broken GFF_ID of my Brocade 200E,
but there may be other switches with different bugs.
Linux also uses GID_PT, but GFF_ID is disabled by default there, and GFT_ID
is not supported.

Also, piping to a shell command does not count as a save, so don't reset

By default LLD links with relocations disallowed against readonly
sections (e.g., .text), but the 32-bit ARM EFI & uboot boot bits require
such relocations. -znotext is either ignored as an unknown -z option
(in-tree lld 2.17.50) or is already the default (GNU ld or GNU gold from
ports) so we can just add it unconditionally to allow building with LLD.
This is similar to the change in r320179 for the kernel link.

--Remove special-case handling of sparc64 bus_dmamap* functions.
Replace with a more generic mechanism that allows MD busdma
implementations to generate inline mapping functions by
defining WANT_INLINE_DMAMAP in <machine/bus_dma.h>. This
is currently useful for sparc64, x86, and arm64, which all
implement non-load dmamap operations as simple wrappers
around map objects which may be bus- or device-specific.
--Remove NULL-checked bus_dmamap macros. Implement the
equivalent NULL checks in the inlined x86 implementation.
For non-x86 platforms, these checks are a minor pessimization
as those platforms do not currently allow NULL maps. NULL
maps were originally allowed on arm64, which appears to have
been the motivation behind adding arm[64]-specific barriers
to bus_dma.h, but that support was removed in r299463.
--Simplify the internal interface used by the bus_dmamap_load*

To find in the leaf bitmap all ranges of sufficient length, use a doubling
strategy with shift-and-and until each bit still set represents a bit
sequence of length 'count', or until the bitmask is zero. In the latter
case, update the hint based on the first bit sequence length not found to
be available. For example, seeking an interval of length 12, the set bits
of the bitmap would represent intervals of length 1, then 2, then 3, then
6, then 12. If no bits are set at the point when each bit represents an
interval of length 6, then the hint can be updated to 5 and the search
terminated.
If long-enough intervals are found, discard those before the cursor. If
any remain, use binary search to find the position of the first of them,
and allocate that interval.
