Subject: kernels: re-enable the b43 and b43-legacy drivers

The b43 and b43-legacy drivers were removed because their
corresponding upstream drivers loads a nonfree firmware.

However linux-libre-firmware has a free firmware
(ucode5.fw) that is used by both drivers.

The b43 and b43-legacy driver are also typically enabled
by Trisquel and Jason Self's linux-libre repository.

Note that some kernel parameters like qos=0 might be
necessary to make it work.

This regression was introduced in linux-libre by the
following commit:
    32075365d upgpkg: libre/linux-libre 4.16.9_gnu-1

The drivers were added back by importing affected parts
from the following upstream kernels and configurations:
- config in linux-armv7 from Arch Linux ARM
- config.i686 in linux from Arch Linux 32
- config from linux from Arch Linux
