[ Upstream commit 9a35d205f466501dcfe5625ca313d944d0ac2d60 ]

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.
