rG4b534b814aa0: acpi: Fix not calling AcpiLeaveSleepState() in S3 path

Summary

When resuming from ACPI suspend, the ACPI_SS_SLP_PREP bit in slp_state
was being checked and subsequently unset when calling resumeclock().
This bit was also being checked for the AcpiLeaveSleepState() call in
the non-s2idle path, but having just been unset, it was never actually
being called.

Change this so that resumeclock() is always being called (since we never
goto breakout between suspendclock() and resumeclock() anyway) and
ACPI_SS_SLP_PREP is purely used for AcpiEnterSleepStatePrep() and
AcpiLeaveSleepState() in the non-s2idle paths.
