soc/amd: Refactor some ACPI S3 calls
Do not pass ACPI S3 state as a parameter, by locally
calling acpi_is_wakeup_s3() compiler has better chance
for optimizing HAVE_ACPI_RESUME=n case.
Test for acpi_s3_allowed() is already included in the
implementation of acpi_is_wakeup_s3() and is removed
as redunandant.
For ramstage, acpi_is_wakeup_s3() evaluates to
romstage_handoff_if_resume().
