[PATCH] x86: Move P2SB from Apollo Lake to a more generic location

[Wolfgang Wallner]

The Primary to Sideband Bridge (P2SB) is not specific to Apollo Lake, so
move its driver to a common location within arch/x86.

This commit follows a similar rational as the recent moving of the ITSS
driver from Apollo Lake to the intel_common directory, and it also depends
on those patches (which are currently in u-boot-x86).
