[RFC: 2.6 patch] move rtc_interrupt() prototype to rtc.h

[RFC: 2.6 patch] move rtc_interrupt() prototype to rtc.h

[Adrian Bunk]

This patch moves the rtc_interrupt() prototype to rtc.h and removes the 
prototypes from C files.

It also renames static rtc_interrupt() functions in 
arch/arm/mach-integrator/time.c and arch/sh64/kernel/time.c to avoid 
compile problems.
