The pnv_pic_print_info() callback checks the type of the chip in order
to forward to the request appropriate interrupt controller. This can
be achieved with QOM. Introduce a method for this in the base chip class
and implement it in child classes.
This also prepares ground for the upcoming interrupt controller of POWER10
chips.
