[PATCH v2 05/10] Add RGB666_1X24_CPADHI media bus format

[Philipp Zabel]

Commit 9e74d2926a28 ("staging: imx-drm: add LVDS666 support for parallel
display") describes a 24-bit bus format where three 6-bit components each
take the lower part of 8 bits with the two high bits zero padded. Add a
component-wise padded media bus format RGB666_1X24_CPADHI to support this
connection.
