[PATCH] change misleading EFI partition support description

Remove the misleading "Presently only useful on the IA-64 platform" text
from the EFI partition Kconfig.

EFI partitions are also used by Apple on their Intel-based machines and
thus you need EFI partition support if you (for example) want to attach
such a machine in target disk mode.
