acpi_scan_device_not_present() is called when a device in the
hierarchy is not available for enumeration. Historically enumeration
was only based on whether the device was present.

To add support for only enumerating devices that are both present
and enabled, this helper should be renamed. It was only ever about
enumeration, rename it acpi_scan_device_not_enumerated().

No change in behaviour is intended.

Is this another patch which ought to be submitted without waiting
for the rest of the series?

Thanks.

Looks like a valid standalone change to me.
