We currently use a spinlock (bit_lock) around operations that clock bits out of the FSI bus, and a mutex to protect against simultaneous access to the master. This means that bit_lock isn't needed for mutual exlusion, only to prevent timing issues when clocking bits out. To reflect this, this change converts bit_lock to just the local_irq_save/restore operation.
