Add the mainline SN65DSI83/84 driver

There is a draft for the Texas Instruments SN65DSI83/84 MIPI-to-LVDS chips in the recent 5.14 kernel. Though it is currently an rc kernel it can be used as a source for cherry picking.

The Driver implements the SN65DSI83 chip as a DRM Bridge and thus can use the connected panel description to configure the converter accordingly.

This uses the new driver for the both TANARO setups, fg0700w0dsswagl1 and qp_070wsvgamlli1d.

Following settings are needed:

+CONFIG_DRM_PANEL_LVDS=y
-CONFIG_DRM_TI_SN65DSI84=y
+CONFIG_DRM_TI_SN65DSI83=y

TODO:

• Review this with K&K to get a better harmonization.
