Add a RES0 device to the SSDT to reserve the PCI ECAM area.
This fixes the warning that Linux prints:
acpi PNP0A08:00: [Firmware Bug]: ECAM area [mem 0x40000000-0x4fffffff]
not reserved in ACPI namespace
[SAMI] I noticed that the "Firmware Bug" message is no longer seen, but
instead the following message is now printed
"system 00:00: [mem 0x40000000-0x4fffffff window] could not be reserved"
It appears this is a harmless message and the relevant discussion can be
seen at: https://lore.kernel.org/all/20210603141641.GA17284@lpieralisi/#t
I think it may be better to update the commit message to reference this
discussion and clarify that this is an expected behavior.

Thanks, I've updated the commit message in v2.
