Add support to dynamically switch between dsi video
mode and command mode for MDP3 driver. For a panel which
is configured in video mode and can support command mode,
it would be power efficient to dynamically switch to
command mode on need basis.

The TE GPIO needed on command mode panels has a gpio_func
value of 1. Acquiring resources of this gpio using gpio_request
API might configure this to a common gpio which has
gpio_func value equal to 0. Hence control this gpio using
the gpiomux framework.

The dsi panel driver implements the dsi command send
and receive functions. However, on 8x10, it was using
its own version. This change is to use the functions
defined in the panel driver.

There are two separate dsi host controller drivers currently.
While the h/w specific operations are different, the dsi
command utility functions can be shared as that is purely s/w.
This change is to use the common dsi command utility api.

On command mode panel, panel is refreshing itself using
its own internal memory. Shutting down the dsi clocks
when there is no display update will save power.

This fixes a power leakage due to gpio is not put into
the suspended mode at display off.

Update dsi v2 driver to use GCDB platform
tags and B family panel utility API. This changes
supports complete GCDB kernel dtsi tags
for 8x10. It also removes the panel v2 driver because
switching to B family panel utility removes
panel v2 driver usage.

This adds the continuous splash screen support on
8x10. At the kernel bootup time, display driver
will copy the splash image from the LK to its own
allocated memory, and keep the display on with the
splash image until the first UI update.

The list size was limited to only 255 DSI commands. But for certain
panels, it requires more DSI commands for panel initialization sequence.

DSI clock is the core clock for DSI controller. Turn on the DSI controller
before issuing panel on DSI commands, and switch to DSI command mode before
sending panel off commands.
