[ARM] 5322/1: Fix fastpath issue in mmci.c

Browse source 
Fix fastpath issues

Since mmci_request() can be called from a non-interrupt
context, and does, during kernel init, causing a host
of debug messages during boot if you enable spinlock debugging,
we need to use the spinlock calls that save IRQ flags and
restore them.
