[Aaron Ma]

BugLink: https://bugs.launchpad.net/bugs/2103617

[Impact]
On Intel LNL, after screen is inverted by "gnome-randr modify eDP-1 --rotate inverted"
Move cursor, the screen will get flicker, with the error in dmesg:
xe 0000:00:02.0: [drm] ERROR Fault errors on pipe A: 0x00040080

[Fix]
Intel provided a patch to fix it.
https://patchwork.freedesktop.org/patch/627668/?series=136033&rev=4
https://gitlab.freedesktop.org/drm/xe/kernel/-/issues/3992

[Test]
Tested on Intel LNL and MTL, screens are normal on all rotate mode,
and suspend/resume for 100 times on both LNL and MTL with positive results.

[Where problems could occur]
It may break i915 and xe driver.

SRU for oem-6.11 and plucky which supports LNL.

LP:2103981 already merged the commit:
67a98f7e27ba ("drm/xe/display: Re-use display vmas when possible")
Add the fixed commit in this SRU only for plucky.
