Subject: drm: bridge: fix ANX7625 use of mipi_dsi_() functions

From: Randy Dunlap <rdunlap@infradead.org>

commit ed01fca38717169fcb61bd45ad1c3750d9c40d59 upstream.

The Analogix DRM ANX7625 bridge driver uses mips_dsi_() function
interfaces so it should select DRM_MIPI_DSI to prevent build errors.
