[PATCH 21/37] drm/amd/display: Atom Integrated System Info v2_2 for DCN35

[Aurabindo Pillai]

From: Gabe Teeger <gabe.teeger at amd.com>

New request from KMD/VBIOS in order to support new UMA carveout
model. This fixes a null dereference from accessing
Ctx->dc_bios->integrated_info while it was NULL.

DAL parses through the BIOS and extracts the necessary
integrated_info but was missing a case for the new BIOS
version 2.3.
