[GIT PULL] drm/fsl-dcu: TCON support and fixes for v4.7

[Stefan Agner]

Hi Dave,

This adds very rudimentary TCON (timing controller for raw LCD displays)
support to enable the bypass mode in order to use the DCU controller on
Freescale/NXP Vybrid SoC's.

Additionally the register clock and pixel clock has been separated, but
are currently still enabled and disabled pairwise.

Other than that, fixes and cleanups accross the driver.
