x86/Kconfig: Document CONFIG_PCI_MMCONFIG

Browse source

This configuration option had no help text, so add it.

CONFIG_EXPERT is enabled on some distribution kernels, so people using a
distribution kernel's configuration as a starting point will see this
option.

[ mingo: Standardized the new Kconfig text a bit. ]
