[PATCH 1/2] dt-bindings: display: ti: Convert ti, tpd12s015 to DT schema

Convert the Texas Instruments TPD12S015 HDMI level shifter and
ESD protection chip bindings to DT schema.

During the conversion, the following updates were made:
- Added the 'ti,tpd12s016' compatible string, which is used in
  am57xx device trees.
- The 'gpios' property now allows up to 5 items, as the
  omap5-igep0050 device tree routes additional control pins
  beyond the standard 3 documented in the old text file.
