media: uapi: Add some RGB bus formats for i.MX8qm/qxp pixel combiner

This patch adds RGB666_1X30_CPADLO, RGB888_1X30_CPADLO, RGB666_1X36_CPADLO
and RGB888_1X36_CPADLO bus formats used by i.MX8qm/qxp pixel combiner.
The RGB pixels with padding low per component are transmitted on a 30-bit
input bus(10-bit per component) from a display controller or a 36-bit
output bus(12-bit per component) to a pixel link.
