[PATCH AUTOSEL 5.15 12/15] ACPI: x86: Add a quirk for Dell Inspiron 14 2-in-1 for StorageD3Enable

[Sasha Levin]

From: Mario Limonciello <mario.limonciello@xxxxxxx>

[ Upstream commit 018d6711c26e4bd26e20a819fcc7f8ab902608f3 ]

Dell Inspiron 14 2-in-1 has two ACPI nodes under GPP1 both with _ADR of
0, both without _HID.  It's ambiguous which the kernel should take, but
it seems to take "DEV0".  Unfortunately "DEV0" is missing the device
property `StorageD3Enable` which is present on "NVME".

To avoid this causing problems for suspend, add a quirk for this system
to behave like `StorageD3Enable` property was found.
