Hello all,

I was building a kernel for x86 and noticed Make still descended into
directories like drivers/gpu/drm/hisilicon, this seems kind of odd given
nothing will be built here. It looks to be due to some directories being
included in obj-y unconditionally instead of only when the relevant
CONFIG_ is set.

These patches are split by subsystem in-case, for some reason, a file in
a directory does need to be built, I believe I have checked for all
instances of this, but a quick review from some maintainers would be nice.

Thanks,
Andrew
