drm/omap: fix missing scaler pixel fmt limitations
OMAP2 and OMAP3/AM4 have limitations with the scaler:
- OMAP2 can only scale XRGB8888
- OMAP3/AM4 can only scale XRGB8888, RGB565, YUYV and UYVY
The driver doesn't check these limitations, which leads to sync-lost
floods.
This patch adds a check for the pixel formats when scaling.
