* [PATCH i-g-t] lib/intel_pat: Cache PAT config for unprivileged processes

From: Himanshu Girotra <himanshu.girotra@intel.com>

Commit 4e59b8e7779b ("lib/intel_pat: use kernel debugfs as
authoritative PAT source for Xe") changed the Xe PAT lookup to
read from debugfs, which requires root access. Some xe_oa subtests
fork a child process that drops root privileges before performing
GPU operations that internally need the PAT write-back index.
After dropping root, the debugfs read fails.

Fix this by caching the PAT configuration on first access. A new
precache helper lets tests populate the cache while still running
as root, so later lookups succeed without debugfs.

This is not correct. The cache should be maintained as part of 'struct
xe_device'.  All tests, include xe_oa, already call xe_device_get(). The
code in lib/intel_pat.c can also call xe_device_get() to check if pat
entries are cached.

As mentioned above, this is not needed if the cache is maintained as part
of 'struct xe_device' since xe_device_get() is being called above.
