dt-bindings: display/msm: hdmi: split and convert to yaml

Convert Qualcomm HDMI binding into HDMI TX and PHY yaml bindings.

Changes to schema:
HDMI:
 - fixed reg-names numbering to match 0..3 instead 0,1,3,4
 - dropped qcom,tx-ddc-* from example, they were not documented
 - make phy-names deprecated, drop it from the examples

PHY:
 - moved into phy/ directory
 - split into QMP and non-QMP PHY schemas
