ppc/pnv: make pnv_ics_get() use the chip8->phbs[] array 

The function is working today by getting all the child objects of the
chip, interacting with each of them to check whether the child is a PHB,
and then doing what needs to be done.

We have all the chip PHBs in the phbs[] array so interacting with all
child objects is unneeded. Open code pnv_ics_get_phb_ics() into
pnv_ics_get() and remove both pnv_ics_get_phb_ics() and the
ForeachPhb3Args struct.
