Subject: [PATCH] ppc: select HAVE_PATA_PLATFORM in PPC instead of creating a PPC dependency

Commit cc18e0fea790 ("LIBATA: Add HAVE_PATA_PLATFORM to select
PATA_PLATFORM driver") introduces config HAVE_PATA_PLATFORM, and expects
that all architectures simply select this config when the architecture
supports using the PATA_PLATFORM driver.

This is properly implemented already for all architectures except for the
powerpc architecture. Implement this for powerpc now.

Adjust the config of the powerpc architecture to use the config
HAVE_PATA_PLATFORM and simplify the config PATA_PLATFORM to not mention
any specific architecture anymore.
