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