add actual platform probing based on PVR. Still needs a little more work:
in particular, the CCRS setup should move here.
Also turn "bare" into a truly bare platform that doesn't pretend to know how
to do anything except get the memory map. This should also be enhanced to
process the FDT reserved memory list, but that is for another day.
assumed that the MDIO bus was a direct child of the Ethernet interface. It
may not be and indeed on many device trees is not. While here, add proper
locking for MII transactions, which may be on a bus shared by several MACs.

unlocked route. Use in6_rtalloc() instead of in6_rtalloc1. This helps
simplify the code and remove several now unused variables.

NIC and pushed up to the driver. Unfortunately this means there's
no rate control notification done. Thus, if the rate control code
makes a decision that hits a crappy rate that can't succeed, the
rate code would never lower the rate and packet loss would continue.
So, fake some rate control notification in this case.
Without this, a far away station with low signal strength would
associate using the management rate (by default the lowest rate)
and then the EAPOL frames would go out at the current AMRR best
guess. This would result in association failing authentication.
Tested:
* Intel 5100, STA
* Intel 2230, STA
The effects of this patch would only be noticeable if you were purposefully
setting a bad value and trying to see what happens; and leaving the disks
intact if a bad value has been set seems fair.
When bsdinstall(8) sources the bsdconfig(8) common.subr file,
PKG_ABI is set by calling 'pkg -vv' and searching for the ABI
pkg(8) will use.
When pkg(8) is run for the first time, the bootstrap process
is run, which prompts for 'y/N' input from stdin if running with
TERM set.
Since TERM is set and it is the first time pkg(8) is run, which
happens automatically, bsdinstall(8) hangs waiting for user input
which is never displayed since a specific line is expected by
awk(1), and stdin is expected by pkg(8).
Set ASSUME_ALWAYS_YES=1, which will cause pkg(8) to assume the
'-y' flag is also used for the bootstrap process, allowing
bsdinstall(8) to proceed to the keymap lookup, otherwise
bsdinstall(8) appears to hang after selecting 'Install' from the
menu on first boot from CDROM.
pin 2 of the IOAPIC.
Add an 'Interrupt Source Override' entry to the MADT to describe this
and start asserting interrupts on pin 2 in the 8254 device model.

- Process ATIO queue only if interrupt status tells so;
- Do not update queue out pointers after each processed command, do it
only once at the end of the loop.
These are largely syntactic sugar. However, they improve code
readability where an RB_FOREACH() or RB_FOREACH_REVERSE()
traversal has been interrupted and must be resumed. Performance
is improved by avoiding unnecessary traversal from the head node.
every time. The purpose of that register is unlikely output queue overflow
detection, so read it only when its last known (and probably stale now)
value signals overflow.
This reduces CPU load and lock congestion and rises bottleneck in CTL
while doing target mode via two 8Gbps ports from 100K to 120K IOPS.
- Fix LOR and possible lock recursion when handling high-power commands.
Introduce new lock to protect left power quota and list of frozen devices.
- Correct locking around xpt periph creation.
- Remove seems never used XPT_FLAG_OPEN xpt periph flag.
