ACPI: Change acpi_device_always_present() into acpi_device_override_status()
[ Upstream commit 1a68b346a2c9969c05e80a3b99a9ab160b5655c0 ]
Currently, acpi_bus_get_status() calls acpi_device_always_present() to
allow platform quirks to override the _STA return to report that a
device is present (status = ACPI_STA_DEFAULT) independent of the _STA
return.
In some cases it might also be useful to have the opposite functionality
and have a platform quirk which marks a device as not present (status = 0)
to work around ACPI table bugs.
Change acpi_device_always_present() into a more generic
acpi_device_override_status() function to allow this.
