Bug description:

  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).


  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.


  After installed proposed package libegl-mesa0, reboot system.

  GUI crashed but still able to access system by ssh.

  [Steps to reproduce]
  1. Boot into OS
  2. sudo apt update
  3. sudo apt upgrade
  4. After upgrade process finished, reboot system.
  5. GUI crashed.

  [Expected result]
  GUI displayed normally

  [Actual result]
  GUI crashed

  [Failure rate]

  Tester comments
  if we don't upgrade libegl-mesa0, GUI will be fine.
