msm: camera: isp: Fix camif raw only snapshot usecase 



For camif raw only usecase, user space does not configure reg_update.
Configure it in kernel when epoch irq is received. Currently, frame
skip registers are configured in both epoch irq routine and sof
routine. This causes frame skip not applied properly. Remove it from
sof irq routine.
