ppc/pnv: make pnv_ics_resend() use chip8->phbs[]

pnv_ics_resend() is scrolling through all the child objects of the chip
to search for the PHBs. It's faster and simpler to just use the phbs[]
array.

pnv_ics_resend_child() was folded into pnv_ics_resend() since it's too
simple to justify its own function.
