[nrf fromlist] modules: hal_nordic: nrfs: Fix init priority

In 7579ccc (modules: hal_nordic: nrfs: Fix initialization priority)
used wrong priority as it assumed that NRFS is using IPC service init
priority. Priorities are fixed now and static assert is added to ensure
that NRFS init priority is higher than IPC service.
