[PATCH] drm/xe/debugfs: Do not register residency files for SRIOV VF

[Gustavo Sousa]

Registers accessed by the recently added[1] residency counters debugfs
are marked as inaccessible to SRIOV VFs. That causes warnings to be
raised when an attempt is made to read those files. Skip registering
those files for VFs.

[1] Via commit 487579fd8524 ("drm/xe/xe_debugfs: Exposure of G-State and
    pcie link state residency counters through debugfs").
