[RFC 03/21] media: vsp1: Set format to RPF input source

[Ulrich Hecht]

From: Koji Matsuoka <koji.matsuoka.xm at renesas.com>

The output format of the RPF must be unified in RGB or YCbCr by
specification of the H/W. To unify the output format in RGB in
driver, if the input format is YCbCr, the output format must be
converted to RGB by CSC (Color Space Conversion).
The driver is missing the format setting of the RPF input source,
so it does not pass through the process to enable the CSC.
This patch adds format setting of the RPF input source.
