Make the following changes in the HDMI gpio bindings:

- Use "-gpios" as the suffix for all the gpio names
- Move all the gpios to optional, since there are platforms that use none
  of them.
- The HPD gpio is a standard one, remove the "qcom,hdmi-tx-" prefix from
  it.
- Remove the HDMI DDC clk/data gpios. They are just leftovers of an old
  way to configure pinctrl properties.
- Add a missing lpm gpio used on some platforms.

Make the necessary changes in the driver to incorporate these changes.

There hasn't been any upstream DT that uses the HDMI bindings, so it's
okay to change and move around these properties.

The MDP4/5 DT node now contains a list of ports that describe how it
connects to external encoder interfaces like DSI and HDMI. These follow
the standard of_graph bindings, and allow us to get rid of the 'connectors'
phandle that contained a list of all the external encoders connected to
MDP.

Add a new doc for DT bindings for platforms that contain MDP5 display
controller hardware. The doc describes bindings for the top level
MDSS wrapper hardware and MDP5 itself.

Add an example for the bindings as found in MSM8916.

The PLL in the DSI PHY block generates 2 clock outputs (Byte and Pixel
clocks) that are fed into the Multimedia Clock Controller (MMCC). The MMCC
uses these as source clocks for some of its RCGs to generate clocks that
finally feed to the DSI host controller.

Use the assigned clocks DT bindings to set up the MMCC RCGs that feed to
the DSI host. Use the DSI PHY provided clocks to set up the parents
of these assigned clocks.

The DSI node now has two ports that describe the connection between the
MDP interface output and the DSI input, and the connection between the DSI
output and the connected panel/bridge. Update the properties and the
example.

Also, use generic PHY bindings instead of the custom one.

The "qcom,data-lane-map" binding mentioned in the document is changed to
the more generic "data-lanes" property specified in:

Documentation/devicetree/bindings/media/video-interfaces.txt

The previous binding expressed physical to logical data lane mappings,
the standard "data-lanes" binding uses logical to physical data lane
mappings. Update the docs to reflect this change. The example had the
property incorrectly named as "lanes", update this too.

The MSM DSI DT bindings aren't used anywhere at the moment, so
it's okay to update this property.

Address some issues wiht clock related bindings. It's okay to change these
since these bindings aren't used in any dtsi files until now.

MDP5:
- Don't ask for source clock

MDP4:
- Give a better name for MDP_TV_CLK
- Remove TV_SRC
- Add MDP_AXI_CLK

The DSI driver is currently unaware of how the DSI physical data lanes
are mapped to the logical lanes provided by the DSI controller.

Create a DT binding "qcom,data-lane-map" that provides this information
on a given platform.

The MSM DSI controller is restricted in terms of what all mappings
it can support. The lane polarity is fixed for all the lanes, the clock
lanes are fixed, and the data lanes can be swapped among each other only
for a few combinations. Apply these restrictions when we parse the DT
data.
