ACPI: x86: Add a quirk for Dell Inspiron 14 2-in-1 for StorageD3Enable
[ 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.
