[PATCH] drm/xe/display: Remove invalid initial plane PTE check for iGPU

[Andrew Zhou <zhoulol888@gmail.com>]

Pantherlake intergrated graphics can have the XE_GGTT_PTEDM bit set
in the BIOS-initialised framebuffer PTE. The new validation rejects
this and fails to create the initial frambuffer, resulting in static.

Remove the too-strict validation.
