Subject: [PATCH v3 05/10] drm/msm/dsi: dsi_cfg: Merge SC7180 config into
 SDM845

The configs are identical, other than the number of *maximum* DSI
hosts allowed. This isn't an issue, unless somebody deliberately
tries to access the inexistent host by adding a dt node for it.

Remove the SC7180 struct and point the hw revision match to the
SDM845's one. On a note, this could have been done back when
7180 support was introduced.
