MLK-16347-3: drm/bridge: Add Northwest Logic DSI transmitter support
Add support for the NorthWest Logit MIPI-DSI controller found in mx8
platforms: i.MX8qm, i.MX8qxp and i.MX8mq.
The NWL MIPI-DSI driver is implemented as a DRM bridge.
The MIPI-DSI encoder will contain the platform specific changes and will
use this bridge.
