The omap4_ctrl_pad_readl and omap4_ctrl_pad_writel functions have been
removed by commit efde234674 but are still used by the OMAP4 ISS
driver, resulting in a compilation breakage:
drivers/staging/media/omap4iss/iss_csiphy.c: In function 'omap4iss_csiphy_config':
drivers/staging/media/omap4iss/iss_csiphy.c:167:2: error: implicit declaration of function 'omap4_ctrl_pad_writel' [-Werror=implicit-function-declaration]
omap4_ctrl_pad_writel(cam_rx_ctrl,
Fix the problem by using the syscon API to reaplace the control pad API.
Lookup the syscon instance by compatible name for now as the OMAP4 ISS
driver doesn't support DT yet.

This adds a very simplistic driver to utilize the CSI2A interface inside
the ISS subsystem in OMAP4, and dump the data to memory.
Check Documentation/video4linux/omap4_camera.txt for details.
This commit adds CSI receivers support.
