[PATCH] [POWERPC] Add interrupt resource for RTC CMOS driver

[Dale Farnsworth]

> 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.

Please add a comment to the source code (similar to that in changelog)
explaining the reason for the 8.
