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 table2024-05-23T19:10:48+00:00Li Mali.ma@amd.com2024-05-20T10:43:55+00:00urn:sha1:19f0edd897f73c4eebb3b5825d8910f0edfa894e
[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.

Theoretically, it would be possible for a buggy or malicious VBIOS to
overwrite past the bounds of the passed parameters (or its own
workspace); add bounds checking to prevent this from happening.

LPDDR5 channels are 32 bit rather than 64, report the width properly
