drm/msm/dpu: Add SC8180x to hw catalog

Add SC8180x to the hardware catalog, for initial support for the
platform. Due to limitations in the DP driver only one of the four DP
interfaces is left enabled.

The SC8180x platform supports the newly added DPU_INTF_WIDEBUS flag and
the Windows-on-Snapdragon bootloader leaves the widebus bit set, so this
is flagged appropriately to ensure widebus is disabled - for now.
