regulator: Fix !REGULATOR builds of systems using system suspend calls

The system suspend calls (used to synchronize between system suspend of
the CPU and it's PMIC) are called from board code but not stubbed when
regulator is disabled causing build failures in such cases.  This patch
fixes those build failures.
