[PATCH RFC 2/2] drivers: gpu: drm: panel: Add BOE NT51021 driver

[Nickolay Goppen]

Add driver for BOE NT51021-based 8-inch and 10-inch DSI video mode
panels used in Xiaomi Mi Pad 4 and Mi Pad 4 Plus (xiaomi-clover)
tablets.

NT51021-based panels also support content-adaptive brightness control by
generating a PWM signal for backlight driver IC. Content adaptation
means that content grey level scale can be increased while
simultaneously decreasing brightness of the backlight to achieve
same perceived brightness. This makes the power consumption of
backlight be reduced with keeping acceptable display quality.

Both panels are very similar, differences are only in init sequence
and resolution.
