Note that this file is generated through Envytools>rnn>headergen2 tool.
https://github.com/freedreno/envytools/blob/master/rnn/headergen2.c#L246
does indent the "case" statement one more time than the "switch" line.
If I modify this code, all switch/case statements will get modified in the
generated file, and that's not really what I want to do; I only want to
add a the few lines of code needed for MDP5 v1.3 support.
By the way, a lot of checkpatch warnings/errors are already present for
these generated files.

Thanks,
Stéphane.
