Resources described by the FADT aren't really a good fit for the
ACPI motherboard driver.

The motherboard driver cares about PNP0C01 and PNP0C02 devices and
their resources.

The FADT describes some resources used by the ACPI core.  Often, they
are also described by by the _CRS of a motherboard device, but I think
it's better to reserve them specifically in the ACPI osl.c because
(a) the motherboard driver is optional and ACPI uses the resources even
if the driver is absent, and (b) I want to remove the ACPI motherboard
driver because it's mostly redundant with the PNP system.c driver.
