[media] omap3isp: Fix frame number propagation
When propagating the frame number through the pipeline, the frame number must be incremented at frame start by the appropriate IRQ handler. This was properly handled for the CSI2 and CCP2 receivers, but not when the CCDC parallel interface is used. ADD frame number incrementation to the HS/VS interrupt handler. As the HS/VS interrupt is also generated for frames received by the CSI2 and CCP2 receivers, remove explicit propagation handling from the serial receivers.
