d8a4ea350f octeontx2-af: Fix undetected unmap PF error check 
Currently the check for an unmap PF error is always going to be false
because intr_val is a 32 bit int and is being bit-mask checked against
1ULL << 32.  Fix this by making intr_val a u64 to match the type at it
is copied from, namely npa_event_context->npa_af_rvu_ge.

f1168d1e20 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.
