Subject: drm/tidss: fix modeset init for DPI panels
Git-commit: a72a6a16d51034045cb6355924b62221a8221ca3
Patch-mainline: v5.9-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
The connector type for DISPC's DPI videoport was set the LVDS instead of
DPI. This causes any DPI panel setup to fail with tidss, making all DPI
panels unusable.
Fix this by using correct connector type.
