[PATCH v11 11/12] drm/mediatek: dpi: Only enable dpi after the bridge is enabled

From: Guillaume Ranquet <granquet at baylibre.com>
Enabling the dpi too early causes glitches on screen.
Move the call to mtk_dpi_enable() at the end of the bridge_enable
callback to ensure everything is setup properly before enabling dpi.
