08bc2cc4c4 LinuxKPI: cast jiffies_to_msecs() result
jiffies_to_msecs() is expected to return an uint_t.  In order to avoid
changing printf format strings, properly cast the result to the
expected type.

046d8d89ed LinuxKPI: fix WRITE_ONCE(), remove ACCESS_ONCE()
Fix a gcc warning: "to be safe all intermediate pointers in cast from
'...' to '...' must be 'const' qualified [-Wcast-qual]".
Doing what is essentially a __DECONST() adding the uintptr_t gets
rid of the massive amount of warnings we get in LinuxKPI and lets
us see the actual problems a lot better.
This is a follow-up to 74e908b3c6 which
fixed READ_ONCE().
ACCESS_ONCE() seems to be an obsolete KPI these days in Linux and
FreeBSD does not use it either directly so we can entirely remove
it now.

6c92544d7c mt76: import mediatek/mt76 driver
Import ISC-licensed driver parts of mediatek/mt76
assumed to be based on Linux wireless-testing at
a02411a5b98612c12be99349836d99f07db12a77 (tag: wt-2022-11-23).

Complement the driver and LinuxKPI with our own (dummy)
implementations of missing parts (util.h and soc/mediatek/)
as well as changes to make compile on FreeBSD with changes
covered by #ifdef (__FreeBSD__) conditions.
Further select updates were applied since the initial import
in order to keep compiling along with other LinuxKPI based
drivers.

For the moment we only target the mt7915 and mt7921 PCI parts.
More may follow in the future.

Firmware is provided by port net/wifi-firmware-mt76-kmod.

Given the lack of full license texts on non-local files this is
imported under the draft policy for handling SPDX files (D29226). [1]

3f686532c9 linuxkpi: Fix __sg_alloc_table_from_pages loop
Commit 3e0856b63f updated
__sg_alloc_table_from_pages to use the same API as linux, but modified
the loop condition when going over the pages in a sg list. Part of the
change included moving the sg_next call out of the for loop and into the
body, which causes an off by one error when traversing the list. Since
sg_next is called before the loop body it will skip the first element
and read one past the last element.

This caused panics when running PRIME with nvidia-drm as the off-by-one
issue causes a NULL dereference.
