[Skiboot] [PATCH] phb4: Additional RXE_ARB: DEC Stage Valid Error fix

[Michael Neuling]

In this recent fix:
  8b4c7a3cef phb4: Mask RXE_ARB: DEC Stage Valid Error
We worked around a problem but the workaround wasn't complete.

Now that we have full documentation and details on the issue, we have
additional registers we need to change inits on.
