[ARM] pxa: factor pxamci gpio handling

Several boards use always the same pattern with pxamci :
request gpio, request irq for that gpio to detect MMC card
insertion, request gpio for read-only mode detection, etc
...

Now that pxamci provides platform_data to describe simple
gpio management of the MMC external controls, use it.
