The IPU formats are stored in two separate tables, one for YUV and one
for RGB formats. This complicates the lookup and enumeration function
without really increasing efficiency, as both tables contain a single
element. Merge the two tables and simplify the functions, and move the
resulting table next to the functions that use it.
