occ: Fix potential race when clearing occ interrupt status
Currently, the occ_interrupt handler will clear the interrupt bit along
with the interrupt reason. If an irq has occurred between the read and
the clear, we'll mask out interrupt bit for that new event
This change checks the reason bits after clearing the interrupt bit. If
any are set, we re-set the interrupt bit to trigger another interrupt.
