  Add the yaml binding for ARM's Mali-C55 Image Signal Processor.

Changes in v5:

	- None

Changes in v4:

	- Switched to port instead of ports

Changes in v3:

	- Dropped the video clock as suggested by Laurent. I didn't retain it
	for the purposes of the refcount since this driver will call .s_stream()
	for the sensor driver which will refcount the clock anyway.
	- Clarified that the port is a parallel input port rather (Sakari)

Changes in v2:

	- Added clocks information
	- Fixed the warnings raised by Rob
