pata_platform: Remove CONFIG_HAVE_PATA_PLATFORM's dependencies.

CONFIG_HAVE_PATA_PLATFORM, by virtue of where its defined, has a
dependency on CONFG_ATA and CONFIG_ATA_SFF.  This causes Kconfig
warnings when it is selected by various architectures, such as

  warning: (ARCH_VEXPRESS && <choice> || ARCH_RPC && <choice> || MACH_VPAC270 && ARCH_PXA || MACH_REALVIEW_PB11MP && ARCH_REALVIEW || MACH_REALVIEW_PBA8 && ARCH_REALVIEW || MACH_REALVIEW_PBX && ARCH_REALVIEW || MACH_BAST_IDE && ARCH_S3C2410 || MACH_ANUBIS && ARCH_S3C2410) selects HAVE_PATA_PLATFORM which has unmet direct dependencies (ATA && ATA_SFF)

Since this option is only used to control visibility of the
CONFIG_PATA_PLATFORM option and isn't itself visible in the menu,
it is straightforward to simply remove these dependencies rather
than adjust all the architectures.
