[PATCH] omap_cf works again (sync with linux-omap tree) 

This syncs the omap_cf driver with the one from the linux-omap tree.  Changes
include fixing build warnings (section mismatch, unused return value) and
coping with various pcmcia core changes related to managing i/o memory and irq
resources.
