[PATCH RFC/DO NOT MERGE 06/12] dt-bindings: display/msm: eliza-hdmi-phy: Add Eliza HDMI PHY

[Krzysztof Kozlowski]

Qualcomm Eliza SoC comes with an Synopsys HDMI phy, unlike previous
variants with HDMI support, thus no compatibility is expressed.  There
is no documentation, except register list and register programming
sequence, and downstream sources do not point to any supplies.
