[POWERPC] Use mpc8641hpcn PIC base address from dev tree.
After going through the trouble of setting up the PIC base address in the pic@40000 device tree node, use it instead of the obsolete hard-coded value. Signed-off-by: Jon Loeliger <jdl@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
