platform/x86: Remove "X86 PLATFORM DRIVERS - ARCH" from MAINTAINERS

platform/x86: Remove "X86 PLATFORM DRIVERS - ARCH" from MAINTAINERS

It seems traffic there is quite low and changes are often not related
to PDx86 anyhow. Besides that I have a lot of other stuff to do, I'm
rearly pay attention on these emails. Doesn't seem Daren to be active
either. With this in mind, remove (stale) section.

Note, it might be make sense to actually move that folder under PDx86
umbrella (in MAINTAINERS) if people find it suitable. That will reduce
burden on arch/x86 maintenance.
