 NPA Reporters

-The NPA reporters are responsible for reporting and recovering the following group of errors
+The NPA reporters are responsible for reporting and recovering the following group of errors:
+
 1. GENERAL events
+
    - Error due to operation of unmapped PF.
    - Error due to disabled alloc/free for other HW blocks (NIX, SSO, TIM, DPI and AURA).

 2. ERROR events

    - Fault due to NPA_AQ_INST_S read or NPA_AQ_RES_S write.
    - AQ Doorbell Error.

 3. RAS events
