msm: camera: Add protection for IRQ storm
msm: camera: Add protection for IRQ storm

VFE composite irq 3 is handled by CAMSS
microcontroller. If microcontroller goes into bad
state and does not clear out irq status bit, there
would be irq storm and result in watchdog bite.
This change ensures if the bits are not clear by
microcontroller, the vfe driver will clear the bits.
