As per recommendation in the workarounds:
WA_22019338487
There is an issue with accessing Stolen memory pages due a
hardware limitation. Limit the usage of stolen memory for
fbdev for LNL+. Don't use BIOS FB from stolen on LNL+ and
assign the same from system memory.
v2: Corrected the WA Number, limited WA to LNL and
Adopted XE_WA framework as suggested by Lucas and Matt.
v3: Introduced the waxxx_display to implement display side
of WA changes on Lunarlake. Used xe_root_mmio_gt and
avoid the for loop (Suggested by Lucas)
v4: Fixed some nits (Luca)
