media: ov5640: Adjust format to bpp in s_fmt
The ov5640 driver supports different sizes for different mbus_codes.
In particular:
- 8bpp modes: high resolution sizes (>= 1280x720)
- 16bpp modes: all sizes
- 24bpp modes: low resolutions sizes (< 1280x720)
Adjust the image sizes according to the above constraints.
