Subject: [PATCH v2] ACPI: x86: Add Cezanne to the list for forcing StorageD3Enable

commit 018d6711c26e4 ("ACPI: x86: Add a quirk for Dell Inspiron 14 2-in-1
for StorageD3Enable") introduced a quirk to allow a system with ambiguous
use of _ADR 0 to force StorageD3Enable.

It was reported that several more Dell systems suffered the same symptoms.
As the list is continuing to grow but these are all Cezanne systems,
instead add Cezanne to the CPU list to apply the StorageD3Enable property
and remove the whole list.

It was also reported that an HP system only has StorageD3Enable on the ACPI
device for the first NVME disk, not the second.
