Subject: drm/i915/guc: drop stage_pool debugfs
Git-commit: 708249a6eba1e1b9c1abfdb400a19f1eb8aaf4d7
Patch-mainline: v5.8-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322

The pool will be private to GuC in the new submission scheme, so we
won't be able to print it and we can just drop the current legacy code.
