Platform: Added a Non-Volatile counters service

This patch introduces a new platform service exposing
the non-volatile counters. Secure partitions can use
this secure API to access the initialisation,
increment and read operations on the nv counters,
by setting "TFM_SP_PLATFORM_NV_COUNTER" as a dependency.
