[PATCH v2 04/11] drm/xe: Add page reclamation info to device info

[Brian Nguyen <brian3.nguyen@intel.com>]

From: Oak Zeng <oak.zeng@intel.com>

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.
