So that we can clean up the header files and not be relying
on implicit includes from device.h ---> module.h

i8259 PIC is disabled on MPC8610HPCD boards, thus currently rtc-cmos
driver fails to probe.
To fix the issue, we lookup the device tree for "chrp,iic" and
"pnpPNP,000" compatible devices, and if not found we do not assign RTC
IRQ and assuming that i8259 was disabled.
Though this patch fixes RTC on some boards (and surely should not break
any other), the whole approach is still broken. We can't easily fix this
though, because old device trees do not specify i8259 interrupts for the
cmos rtc node.

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.

In order to use the RTC CMOS driver, each architecture must register a
platform device for the RTC.
This creates a function to register the platform device based on the RTC
device node and verifies that the RTC port against the hard-coded value
in asm/mc146818rtc.h.
