Kirby: almost final setup for the parade.

Browse source 
Select internal PWM controls (for now) and max brightness.

The code is there for power on timings, but commented out.
If it is ever needed it's going to save some time for future
coders to have it where it is.

BUG=None
TEST=Build, boot, see display.
BRANCH=None
