drm/bridge: ti-sn65dsi83: Add TI SN65DSI83 and SN65DSI84 driver
Add driver for TI SN65DSI83 Single-link DSI to Single-link LVDS bridge and TI SN65DSI84 Single-link DSI to Dual-link or 2x Single-link LVDS bridge. TI SN65DSI85 is unsupported due to lack of hardware to test on, but easy to add. The driver operates the chip via I2C bus. Currently the LVDS clock are always derived from DSI clock lane, which is the usual mode of operation. Support for clock from external oscillator is not implemented, but it is easy to add if ever needed. Only RGB888 pixel format is implemented, the LVDS666 is not supported, but could be added if needed.
