powerpc/powernv: Refactor PHB diag-data dump
As Ben suggested, the patch prints PHB diag-data with multiple
fields in one line and omits the line if the fields of that
line are all zero.
With the patch applied, the PHB3 diag-data dump looks like:

[ The current diag data is so big that it overflows the printk
buffer pretty quickly in cases when we get a handful of errors
at once which can happen. --BenH
