Hi All - 
These patches enhance the current support for MIPI DSI for Baytrail. They
continue on the sub-encoder design and adds few more dev_ops to handle
sequence correctly. Major changes are -
 1. DSI Clock calculation based on pixel clock
 2. Add new dev_ops for better sequencing the enable/disable path
 3. Parameterized the hardcoded DSI parameters. These also forms building
    block for the generic MIPI driver to come in future based on enhancements
    in VBT. All these parameters are initialized or computed in the sub-encoder
    driver. Some of them might look unneccesary for now.

I am also aware of the drm_bridge support now comming in and will in future
migrate from sub-encoder design to drm_bridge.

This DSI sequence has been validated with couple of test panels and is working now.
Still no sub-encoder driver is included and this support will be mostly be disabled
untill a panel sub-encoder driver is added. Proper detection or VBT is still pending.
