Subject: [PATCH] ata: ahci: Revert "ata: ahci: Add Tiger Lake UP{3,4} AHCI
 controller"
References: bsc#1012628
Patch-mainline: 6.2.3
Git-commit: 6210038aeaf49c395c2da57572246d93ec67f6d4

commit 6210038aeaf49c395c2da57572246d93ec67f6d4 upstream.

Commit 104ff59af73a ("ata: ahci: Add Tiger Lake UP{3,4} AHCI
controller") enabled low power mode for the Tiger Lake AHIC adapter in
the author system but created regressions for others. Revert this patch
for now until a better solution is found to make this adapter
eco-friendly.
