[POWERPC] Create add_rtc() function to enable the RTC CMOS driver 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.

[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>

powerpc: rtc_cmos_setup: assign interrupts only if there is i8259 PIC 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.
