The current bank reset implementation polls the INTR_STATUS register
until interested bits are set. This is not good because:
- polling simply wastes time-slice of the thread
- The while() loop may continue eternally if no bit is set, for
example, due to the controller problem. The denali_wait_for_irq()
uses wait_for_completion_timeout(), which is safer.
We can use interrupt by moving the denali_reset_bank() call below
the interrupt setup.
