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.

Our hardware only supports the YUV planes order and in order to support formats with a YVU plane order, a helper is introduced to indicate whether to invert the address of the two chroma planes. Missing definitions for YUV411 and YUV444 input format configuration are also introduced as support is added for these formats. For the input sequence part, no configuration is required for planar YUV formats so zero is returned in that case.
