Now that patch 2-5 landed in phy-next, patch 1 is needed to explicitly
set MIPI DPHY mode in the nwl-dsi drm bridge driver, otherwise, i.MX8mq
MIPI DSI display feature will be broken due to the phy mode check added
in patch 5.

I'm assuming patch 1 should go through drm-misc. Robert/drm folks, can
you please pick it up?

Thanks,
Liu Ying
