The P2SB library is used for various drivers, including server
platforms. That's why the dependency on X86_PLATFORM_DEVICES
seems superfluous.

This needs to become "PCI && X86" to avoid this possible getting
enabled on other platforms.

With that added you may add my:

and this also counts as my ack for merging this through
Lee's MFD tree together with the rest of the series.
