[PATCH] Add configuration to specify availability of pata_platform

[PATCH] Add configuration to specify availability of pata_platform

[Ben Dooks]

Add a hidden configuration for an architecture or machine to
select to show that the pata_platform driver should be show
in the configuration.

This method is used to allow each individual machine/arch to
specify this, instead of creating large "depends on" on the
driver's Kconfig menu.

If this patch is acceptable, I will submit a patch to
move ARCH_RPC to select ARCH_HAS_PATA_PLATFORM.
