Add driver for the Intersil ISL7998x Analog to MIPI CSI-2/BT656 decoder. This chip supports 1/2/4 analog video inputs and converts them into 1/2/4 VCs in MIPI CSI2 stream. This driver currently supports ISL79987 and both 720x480 and 720x576 resolutions, however as per specification, all inputs must use the same resolution and standard. The only supported pixel format is now YUYV/YUV422. The chip should support RGB565 on the CSI2 as well, but this is currently unsupported.
