stable inclusion from stable-v5.10.84 commit 9a32d3c08d8ee2c3bf005399bbe17ca71d2536ea bugzilla: 186030 https://gitee.com/openeuler/kernel/issues/I4QV2F
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit 1527f69204fe35f341cb599f1cb01bd02daf4374 ]
AMD requires that the SATA controller be configured for devsleep in order for S0i3 entry to work properly.
commit b1a9585cc396 ("ata: ahci: Enable DEVSLP by default on x86 with SLP_S0") sets up a kernel policy to enable devsleep on Intel mobile platforms that are using s0ix. Add the PCI ID for the SATA controller in Green Sardine platforms to extend this policy by default for AMD based systems using s0i3 as well.
