[PATCH v2 3/4] dt-bindings: display: Add Novatek NT35596 panel documentation

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 only 4 regulators
like VCI, VDDI/DVDD, AVDD, AVEE are used during power-on sequence.

Out of four regulators MTF050FHDI-03 panel do support 3-regulator based
power-on sequence, so this patch documented these 3 needful regulators
and rest can be add while supporting new panels on the similar chip IC.
