Various pieces of information about DRM formats (number of planes, color depth, chroma subsampling, ...) are scattered across different helper functions in the DRM core. Callers of those functions often need to access more than a single parameter of the format, leading to inefficiencies due to multiple lookups. Centralize all format information in a data structure and create a function to look up information based on the format 4CC.
