msm: camera: isp: Handle RUP in applied substate

In RDI only context, if RUP is received earlier than SOF,
the state machine is set to applied state and there is no
handling for RUP in applied substate. Hence leading to
bubble scenario and apply failures.

To overcome such scenario, handling for RUP in applied
substate is introduced in RDI only context statemachine.
In this handling, substate is moved to EPOCH so when
SOF is scheduled next state machine moves in right
direction.
