This patch adds two new functions:
- disable_dsi_pll.
BXT DSI disable sequence and registers are
different from previous platforms.
- intel_disable_dsi_pll
wrapper function to re-use the same code for
multiple platforms. It checks platform type and
calls appropriate core pll disable function.
v2: Fixed Jani's review comments.

Kerneldoc for the entire dsi subsystem would be awesome ... are you
working on that too?

Hi Daniel,
Yes that would be really good document to have. Currently not working on
that, but will take this up and create a documentation for DSI subsystem
along with generic mipi sequence parsing from VBT and backlight control.

Uma Shankar
