Subject: drm/i915/rpm: Enable runtime pm autosuspend by default
Git-commit: 527bab0473f28236e4587c7870586275c1ef5516
Patch-mainline: v5.17-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
Let's enable runtime pm autosuspend by default everywhere.
So, we can allow D3hot and bigger power savings on idle scenarios.
But at this time let's not touch the autosuspend_delay time,
what caused some regression on our previous attempt.
Also, the latest identified issue on GuC PM has been fixed by
commit 1a52faed3131 ("drm/i915/guc: Take GT PM ref when deregistering
context")
v1: Enable runtime pm autosuspend by default for Gen12
and later versions.
v2: Enable runtime pm autosuspend by default for all
platforms(Syrjala Ville)
v3: Change commit message(Nikula Jani)
