PXA: Remove PXA PCMCIA support

Say good bye to some ancient, very broken and unused code.

-These are brief instructions on how to add support for CF adapters to
-custom designed  PXA boards. You need to set the parameters in the
-config file. This should work for most implementations especially if you
-follow the connections of the standard lubbock. Anyway just the block
-marked memory configuration should be touched since the other parameters
-are imposed by the PXA architecture.
-
-EDIT 2010-07-01: in common/cmd_ide.c, having CONFIG_PXA_PCMCIA defined
-would cause looping on inw()/outw() rather than using insw()/outsw(),
-thus making sure IDE / ATA bytes are properly swapped. This behaviour
-is now controlled by CONFIG_IDE_SWAP_IO, therefore PXA boards with
-PCMCIA should #define CONFIG_IDE_SWAP_IO.
