OMAP3: PRCM interrupt: only check and clear enabled PRCM IRQs
While handling PRCM IRQs, mask out interrupts that are not enabled in
PRM_IRQENABLE_MPU. If these are not masked out, non-enabled
interrupts are caught, a WARN() is printed due to no 'handler' and the
events are cleared. In addition to being noisy, this can also
interfere with independent polling of this register by SR/VP code.
This was noticed using SmartReflex transitions which cause the VPx_*
interrupts to be handled since they are set in PRM_IRQSTATUS_MPU even
but not enabled in PRM_IRQENABLE_MPU.
