[Impact]

In drm/amdgpu fix the mc_data out-of-bounds read warning. This is
done by removing the warning that reads when mc_data[i-1] may be
out-of-bounds.

[Fix]

Noble:	Clean cherry-pick from linux-6.10.y
Jammy:	pending (5.15.0-125.135)
Focal:	pending (5.4.0-200.220)
Bionic:	Clean cherry-pick from linux-4.19.y
Xenial:	Bionic patch applied cleanly.
Trusty:	not-affected

[Test Case]

Compile and boot tested.

[Where problems could occur]

This fix affects those who use AMD AtomBIOS for the AMD
GPU, an issue with this fix would be visible to the user
via a system crash.
