[PATCH 6.18 390/396] drm/xe: Add page reclamation info to device info

6.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Oak Zeng <[email protected]>

[ Upstream commit 9b1a0e0a15c97987fdf56a615f3d13995bafd042 ]

Starting from Xe3p, HW adds a feature assisting range based page
reclamation. Introduce a bit in device info to indicate whether
device has such capability.
