Subject: [PATCH v4 0/9] Multicolor Framwork

Hello!

Here is the multicolor framework reworked with numerous changes.
Most importantly is the ABI to produce a color.

brightness file controls the cluster based on the color intensity set.
The color intensity can be set either through the colors/color_mix file,
which requires all LED values within the cluster to be written or the LED's
intensity can be controlled individually via the colors/<color>/intensity file.

This code has been tested using the LP5523 EVM and the LP50xx evms.  Triggers
work in this model.  I have performed tests to confirm that the color requested
stays consistent when ramping from LED_OFF to LED_FULL and back down to LED_OFF.

I anticipate another round of patches but I would like to get comments on all
the code.

Dan
