ARM: defconfigs for 6.3

As usual, this branch contains all the patches to enable options
for newly added device drivers in the 32-bit and 64-bit defconfig
files.

I have sorted the files according to the changes to Kconfig files,
to make it easier to check what has changed compared to the 'make
savedefconfig' output.

The most notable change this time is a series from Mark Brown
to add a 'virtconfig' target for arm64, which is for the moment
the same as the 'defconfig' target but disables all the top-level
SoC specific options in order to have a smaller and faster
kernel build.
