Hi,

This small series adds support for two new pixel formats for the 
rcar-vin driver; V4L2_PIX_FMT_ARGB555 and V4L2_PIX_FMT_ABGR32. Both 
formats have an alpha component so a new standard control is also added
to control its value, V4L2_CID_ALPHA_COMPONENT.

The series is based on the latest media-tree and is tested on both 
Renesas Gen2 and Gen3 hardware without any regressions found.

Patch 1/3 fixes a badly named register name, 2/3 adds the new control 
and finally 3/3 adds the two new pixel formats.
