Subject: [PATCH] drm/msm/dsi: Allow 2 CTRLs on v2.5.0
Git-commit: 1ae654ded7c5a19dc13f57a4fe4434fef879b6f9
Patch-mainline: v6.3-rc1
References: git-fixes

v2.5.0 support was originally added for SC7280, but this hw is also
present on SM8350, which has one more DSI host. Bump up the dsi count
and fill in the register of the secondary host to allow it to probe.

This should not have any adverse effects on SC7280, as the secondary
CTRL will only be touched if it's defined, anyway.
