[PATCH] pcmcia: at91_cf update

Browse Source 
More correct AT91 CF wakeup logic ... only enable/disable the IRQ wakeup
capability, not the IRQ itself.  That way the we know that the IRQ will be
disabled correctly, in suspend/resume logic instead of ARM IRQ code.

Most of the pin multiplexing setup has moved to the devices.c setup code.
