Add health reporters for RVU NIX block.
NIX 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
   reporter hw_nix_intr
     state healthy error 0 recover 0 grace_period 0 auto_recover true auto_dump true
   reporter hw_nix_gen

   reporter hw_nix_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_nix_intr
  NIX_AF_RVU:
	NIX RVU Interrupt Reg : 1
	Unmap Slot Error
 # devlink health dump show pci/0002:01:00.0 reporter hw_nix_gen
  NIX_AF_GENERAL:
	NIX General Interrupt Reg : 1
	Rx multicast pkt drop

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