Bug description:
[Impact]
OEM-6.1 kernel is missing support for minimum page size of 64k on DG2
(gfx12.5). Mesa 23.2 started using that, so it broke initializing the
gpu on boot, causing a blank screen with no GDM running (with wayland,
and fallback to X failed too).
[Fix]
Revert the commit that allows using 64k page size, since that's what
the current version in jammy-updates is using. OEM-6.1 kernel is going
away, no need to patch that anymore. No other kernel is affected, >6.2
works fine and thus this revert is not necessary in mantic or noble.
[Test case]
Install the update, boot up a machine with DG2 (iGPU or dGPU, doesn't
matter). The login screen should appear.
[Where things could go wrong]
Hard to see how this could regress anything, as it just restores the limits
for intel gfx12.5 as they were in the current mesa version in jammy.
