media: tpg: Add function to return colors' order of test image
Currently there is no method to know the correct order of the colors for a test image generated by tpg. Write a function that returns a string of colors' order given a tpg. It returns a NULL pointer in case of test patterns which do not have a well defined colors' order. Hence add a NULL check for text in tpg_gen_text().
