Add SPI mode (PIO-only) support for Intel Synchronous Serial Port that
can be found in several Intel's products starting from PXA family.
Most of implementations have slight differences in behavior and in
addresses for registers subset. This driver covers only BayTrail SoC
implementation for it's the only hardware I have to test it on.
Driver attaches to ACPI bus only and does not have PCI or FDT support
for now due to lack of hardware to test it on.
"intelspi" is the best name I've managed to come up with. Linux driver
name (spi-pxa2xx) does not make sense because current implementation
does not support actual PXA2xx SoCs. And as far as I know there is no
codename assigned to Intel SSP chip.

There was report of stable/11 build failure on older versions of
FreeBSD. The problem was a reference to static variable in inline
function. Although fairly recent versions of clang can cope with this
situation just fine there is no strict requirement to make functions
in question inline, they're not in any time-critical codepath. So to
keep HEAD and 11-STABLE buildable on older FreeBSDs some of the util
functions were converted from inline to normal.

I don't yet know which RX descriptor bits map to shortgi, long-gi,
short-preamble, long-preamble, STBC, LDPC, HT40, etc - so I can't
easily add those just yet.
There's apparently no per-frame RX RSSI information exposed so we
also just use the results from the previous calibration task.
This also tidies up how the per-mbuf RSSI is pushed into the frame -
now that it's attached to the mbuf via rx_stats, we don't have to
do any silly hijinx to get it out of the frame processing path.

Current Xen IPI setup functions require that the caller provide a device in
order to obtain the name of the interrupt from it. With early AP startup this
device is no longer available at the point where IPIs are bound, and a KASSERT
would trigger:
panic: NULL pcpu device_t
cpuid = 0
KDB: stack backtrace:
db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xffffffff82233a20
vpanic() at vpanic+0x186/frame 0xffffffff82233aa0
kassert_panic() at kassert_panic+0x126/frame 0xffffffff82233b10

mi_startup() at mi_startup+0x118/frame 0xffffffff82233b70

Fix this by no longer requiring the presence of a device in order to bind IPIs,
and simply use the "cpuX" format where X is the CPU identifier in order to
describe the interrupt.

FC-Tape provides additional link level error recovery, and is

Add a new kernel config option, ISP_FCTAPE_OFF, that
defaults the FC-Tape configuration to off.

As a fortuitous side effect, checking that these values are non-zero
here results in them not *becoming* zero later on the function. This
odd behaviour began with r309124 (clang 3.9.0) but is challenging to
