media: renesas: rzg2l-cru: Add 'yuv' flag to IP format structure

Browse Source 
Add a 'yuv' flag to the `rzg2l_cru_ip_format` structure to indicate
whether a given format is YUV-based and update the `rzg2l_cru_ip_formats`
array with this flag appropriately. This change enables a more efficient
way to check if the input and output formats use the same colorspace.

With this change, we can eliminate the use of `v4l2_format_info()` in
`rzg2l_cru_initialize_image_conv()` as the necessary details for the source
and destination formats are already available through the `yuv` flag.
