[PATCH v4 04/10] media: staging: rkisp1: don't support bayer format on selfpath resizer

[Dafna Hirschfeld]

The selfpath capture does not support bayer formats.
Therefore there is no reason to support bayer formats
on the selfpath resizer. The selfpath resizer should
support only MEDIA_BUS_FMT_YUYV8_2X8.
