Under certain circumstances a hw_scan may be downgraded to a software
scan. Handle these situations better and make sure we free resources
in all cases once. [1]
Also leave a note about scanning all bands (or we would have to switch
bands manually).
In both cases hardware doing and driver saying seem not entirely
consistent for all and all firmware.

Fix a gcc warning: "to be safe all intermediate pointers in cast from

Doing what is essentially a __DECONST() adding the uintptr_t gets

us see the actual problems a lot better.
This is a follow-up to 74e908b3c6 which

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.

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

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.

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.
