Public bug reported:

[ Impact ]

 * On ARL-H, the GPU isn't supported in 6.8. As such, display is using
the simpleframebuffer driver which doesn't handle going into suspend and
other issues.

[ Fix ]
 * Add support of the GPU to 6.8. As ARL-H is reusing MTL design, adding the 
PCI ids and few tweaks is enough to enable it. As such, 5 upstream commits that 
landed in 6.9 are needed :
 84bf82f4f8661 drm/i915/xelpg: Extend driver code of Xe_LPG to Xe_LPG+
 c5b32a4194613 drm/i915/xelpg: Add workaround 14019877138
 6d46d09a0d7dd drm/i915/mtl: Wake GT before sending H2G message
 93cbc1accbcec drm/i915/mtl: Add fake PCH for Meteor Lake
 bddacdf4861c0 drm/i915: Add additional ARL PCI IDs

[ Test Plan ]

 * Boot ARL-H hardware and verify that the i915 is loaded.
   Check that the screen is correctly working, go into suspend, wakeup and 
verify it's still working.

[ Where problems could occur ]

 * Regression in i915 module and display issues.

[ Other Info ]

 * Initially reported there https://bugs.launchpad.net/kobuk/+bug/2111690
 * Official intel GPU support table : 
https://dgpu-docs.intel.com/devices/hardware-table.html
 * This only target Noble as those patches were added in 6.9.
