powerpc/86xx: mpc8610_hpcd - add support for ULI RTC

The ULI "Super South Bridge" contains ISA bridge to the legacy
devices, such as Super IO mouse/keyboard/floppy disk controllers,
parallel port, i8259 interrupt controller and so on.

i8259 is disabled on the MPC8610HPCD, and other peripherals are not
traced out. So we use only RTC.
