6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Li Ma li.ma@amd.com
commit e64e8f7c178e5228e0b2dbb504b9dc75953a319f upstream.
[Why] The vram width value is 0. Because the integratedsysteminfo table in VBIOS has updated to 2.3.
[How] Driver needs a new intergrated info v2.3 table too. Then the vram width value will be correct.
