Replaces template patching with packages composed using AML API. Note on behavior change: If S3 or S4 is disabled, respective packages won't be created and put into SSDT. Which saves us some space in SSDT and doesn't confuse guest OS with mangled package names as it was done originally. Signed-off-by: Igor Mammedov <imammedo@redhat.com> Reviewed-by: Michael S.
