It is often useful to check whether the DRM format info retrieved from the DRM framebuffer matches a specific YUV planes disposition.
This introduces helpers to quickly check that a provided format info matches a YUV format with a specific disposition, in commonly-used terminology.
The intent of providing helpers taking the format info instead of the fourcc alone is to avoid the overhead of iterating through all formats when the whole format info structure is available. As a result, these helpers are very simple so they are made inline.
