[PATCH 06/15] drm/amd/display: enable fgcg by default

[Aurabindo Pillai]

From: Charlene Liu <charlene.liu at amd.com>

[why]
sw has most of the fgcg enabled which is the same as HW default.
but driver disabled some due to enable flag not initialized.

comparing HW state, we still need to enable dpp and dio.
