ARM: pxa: Access SMEMC via virtual addresses
This is important because on PXA3xx, the physical mapping of SMEMC registers
differs from the one on PXA2xx. In order to get PCMCIA working on both PXA2xx
and PXA320, the PCMCIA driver was adjusted accordingly as well.
Also, various places in the kernel had to be patched to use
__raw_read/__raw_write.
