[ARM] pxa: move PCMCIA definitions out of pxa-regs.h into pxa2xx_base.c

Move the processor specific initialization (largely resources initialization)
out of soc_common_drv_pcmcia_probe() into dedicated sa11xx_drv_pcmcia_probe()
and __pxa2xx_drv_pcmcia_probe().

By doing this, we are now able to move the PCMCIA related definitions out of
pxa-regs.h and back into pxa2xx_base.c.

As a result, remove that reference of _PCMCIA1IO in arch/arm/mach-pxa/viper.c.
