drm/armada: fix irq handling

[ Upstream commit 92298c1cd8e8a6b56322b602ad72b54e6237631d ]

Add the missing locks to the IRQ enable/disable paths, and fix a comment
in the interrupt handler: reading the ISR clears down the status bits,
but does not reset the interrupt so it can signal again.  That seems to
require a write.
