powerpc/powernv: Add PE to its own PELTV

commit 631ad691b5818291d89af9be607d2fe40be0886e upstream.

We need add PE to its own PELTV. Otherwise, the errors originated
from the PE might contribute to other PEs. In the result, we can't
clear up the error successfully even we're checking and clearing
errors during access to PCI config space.
