ADV7481 raises back-to-back interrupts on cable connect and
disconnect. The IRQ bottom half has to check the interrupt status
register in a loop and service all events that have been raised,
rather than relying on the top half getting scheduled for each event.

Add suspend and resume handler to be called from power management
framework for driver to release clock votes prior to device goes
into sleep state. Driver requests for the necessary resources in
resume handler

Add signal lock/unlock interrupts for CVBS input. This
enables to detect when input stream is stop/start due
to reasons such as cable plug out/plugin. Also update
driver code with the new macro added with this patch
and clean up header to move tab to space for consistent
editing/viewing across editors.
