ACPI S3: Remove conflicting local acpi_get_sleep_type() 

We now require EARLY_CBMEM_INIT and romstage_handoff to
support HAVE_ACPI_RESUME. Thus acpi_handoff_wakeup() would
never call an externally defined acpi_get_sleep_type().

Name _sleep_type() was also inapproriate here, as it referred
to hardware-dependent SLP_TYP field of PM1CNT but still
returned ACPI_Sx value instead.
