ARM: pxa: Add GPIO descriptors for Palm27x

Browse Source 
The Palm27x devices set up the MMC card detect and
write protect lines with a special helper function.
Augment this helper function to also accept an optional
GPIO descriptor table and pass and register this for
all the Palm27x devices in that family.
