cx18: Remove unnecessary MMIO accesses in time critical irq handling path
From: Andy Walls <awalls@radix.net>
Remove unnecessary MMIO accesses in time critical irq handling path. Also
ensured that the mailbox ack field is read in last, so we know for sure if we
have a stale mailbox or not on receipt.
Priority: normal
Signed-off-by: Andy Walls <awalls@radix.net>
