[ARM] 5396/1: RealView: Use PATA_PLATFORM to access the CompactFlash

Browse Source 
This driver adds the platform_device definitions to allow the use of
CompactFlash on the RealView PB11MPCore and PB-A8 platforms. Note that
the CompactFlash controller is expected to be initialised by the Boot
Monitor and support the True IDE mode.
