It should be perfectly fine to use ACPI if the "fixed" power or sleep
buttons cannot be initialized. Moreover, running acpi_bus_scan()
successfully on ACPI_ROOT_OBJECT generally causes many devices to
be enumerated and probed, possibly including the entire PCI bus, so
unregistering acpi_root if the registration of the "fixed" buttons
fails is rather unhelpful.
For this reason, do not fail acpi_scan_init() when
acpi_bus_scan_fixed() fails and turn the latter into a void function.
While at it, drop the outdated and misleading comment from
acpi_bus_scan_fixed().
