[PATCH 5.10 015/530] drm: bridge: fix LONTIUM use of mipi_dsi_() functions

From: Randy Dunlap <rdunlap@infradead.org>

commit ad085b3a712a89e4a48472121b231add7a8362e4 upstream.

The Lontium DRM bridge drivers use mipi_dsi_() function interfaces so
they need to select DRM_MIPI_DSI to prevent build errors.
