5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mario Limonciello mario.limonciello@amd.com
commit 64ffd2f1d00c6235dabe9704bbb0d9ce3e28147f upstream.
Originally we were quirking ASPM disabled specifically for VI when used with Alder Lake, but it appears to have problems with Rocket Lake as well.
Like we've done in the case of dpm for newer platforms, disable ASPM for all Intel systems.
