commit f6f49dda49db72e7a0b4ca32c77391d5ff5ce232 upstream.
v3.x changed the how vram width was encoded. The previous
implementation actually worked correctly for most boards.
Fix the implementation to work correctly everywhere.
This fixes the vram width reported in the kernel log on
some boards.

drm/amdgpu/atomfirmware: add intergrated info v2.3 table2024-06-16T11:41:36+00:00Li Mali.ma@amd.com2024-05-20T10:43:55+00:00urn:sha1:97820893f2ad35aa98b04cbaff4d29b617e2836d
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.
