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

Other changes:
 - fixed reg-names numbering to match 0..3 instead 0,1,3,4
 - phy part moved into phy/ directory

Signed-off-by: David Heidelberg <david@ixit.cz>
---
v2:
 - move phy into phy/
 - added maxItems for gpios
 - simplified pinctrl-names
 - dropped some inconsistent quotes
