ppc/pnv: Generate phandle for the "interrupt-parent" property
Devices such as the BT or serial devices require a valid "interrupt-parent" phandle in the device tree and it is currently empty (0x0). It was not a problem until now but since OpenFirmare started using a recent libdft (>= 1.4.7), petitboot fails to boot the system image with error : dtc_resize: fdt_open_into returned FDT_ERR_BADMAGIC Provide a phandle for the LPC bus.
