mpsl: pm: Fix wrong macro to enable integration with MRAM lat service

There was wrong macro used to wrap the core responsible for
integration with MRAM latency service for nRF54h20 SoC.
The macro shoudl be a Kconfig option so that the feature
is enabled with MPSL PM is enabled.

The commit fixes the code.
