Subject: [PATCH 2/3] octeontx2-af: Add devlink health reporters for NPA

Add health reporters for RVU NPA block.
NPA Health reporters handle following HW event groups
 - GENERAL events
 - ERROR events
 - RAS events
 - RVU event

Output:
 #devlink health
 pci/0002:01:00.0:
   reporter hw_npa_intr
     state healthy error 0 recover 0 grace_period 0 auto_recover true
 auto_dump true
   reporter hw_npa_gen
     state healthy error 0 recover 0 grace_period 0 auto_recover true
 auto_dump true
   reporter hw_npa_err
     state healthy error 0 recover 0 grace_period 0 auto_recover true
 auto_dump true
   reporter hw_npa_ras
     state healthy error 0 recover 0 grace_period 0 auto_recover true
 auto_dump true

 #devlink health dump show  pci/0002:01:00.0 reporter hw_npa_err
 NPA_AF_ERR:
        NPA Error Interrupt Reg : 4096
        AQ Doorbell Error
 #devlink health dump show  pci/0002:01:00.0 reporter hw_npa_ras
 NPA_AF_RVU_RAS:
        NPA RAS Interrupt Reg : 0

 Each reporter dump shows the Register value and the description of the
cause.
