drm/bridge: nwl-dsi: Get MIPI DSI controller and PHY ready in ->mode_set()
Some MIPI DSI panel drivers like 'raydium,rm68200' send
MIPI_DCS_SET_DISPLAY_ON commands in panel_funcs->prepare(), which
requires the MIPI DSI controller and PHY to be ready beforehand.
Without this patch, the nwl-dsi driver gets the MIPI DSI controller
and PHY ready in bridge_funcs->atomic_pre_enable(), which happens after
the panel_funcs->prepare(). So, this patch shifts the bridge operation
ealier from bridge_funcs->atomic_pre_enable() to bridge_funcs->mode_set().
This way, more MIPI DSI panels can connect to this nwl-dsi bridge.
