[0/4] drm/panel: Add Novatek NT35596 panel driver

Message

This patch set support Microtech MTF050FHDI-03 MIPI DSI panel, which
has Novatek NT35596 controller IC.

Since there is no proper programming guide for NT35596 IC, the driver 
init sequence is referenced from [1] but analyzed based on datasheet.

NT35596 support several regulators on the chip, among those ony 4
regulators like VCI, VDDI/DVDD, AVDD, AVEE are used during power-on
sequence. Right now driver added code for 3-regulator based power-on
sequence since MTF050FHDI-03 panel support. This power-on sequence may
be moved to panel_desc in future, if there is any new panel would come
up with other type of sequence.

Any inputs?
Jagan.
