[PATCH 3/4] dt-bindings: display: Add Novatek NT35596 panel documentation

[Jagan Teki]

Novatek NT35596 is a single-chip IC solution for small or medium-sized
LTPS TFT LCD panels. NT35596 provides  several system interfaces like
MIPI/SPI/I2C.

Microtech MTF050FHDI-03 is 1080x1920, 4-lane MIPI DSI LCD panel which
has inbuilt NT35596 IC chip.

NT35596 support several regulators on the chip, among those ony 4 regulators
like VCI, VDDI/DVDD, AVDD, AVEE are used during power-on sequence. Since
MTF050FHDI-03 panel do support 3-regulator based power-on sequence, this
patch document only needful regulators and rest can be add while supporting
new panels on the similar chip IC.
