[PATCH 11/26] video: dsi_host: add disable host interface

[Dario Binacchi]

From: Michael Trimarchi <michael at amarulasolutions.com>

Current operations structure has provided disable callback, but
there is no API from dsi_host uclass to use it.

Add this disable host interface, so that dsi bridge can call it
to disable host
