[POWERPC] Add interrupt resource for RTC CMOS driver
The RTC CMOS driver expects the interrupt to be a resource of the platform device. Use a fixed interrupt value of 8 since on PPC if we are using this its off an i8259 which we ensure has interrupt numbers 0..15. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
