[PATCH] ARM: prima2: fix missing <linux/rtc/sirfsoc_rtciobrg.h> in rtciobrg.c

[Ben Dooks]

The header file <linux/rtc/sirfsoc_rtciobrg.h> declares two functions
exported from the rtciobrg.c file, so include it to fix the following
warnings:

arch/arm/mach-prima2/rtciobrg.c:41:6: warning: symbol 'sirfsoc_rtc_iobrg_besyncing' was not declared. Should it be static?
arch/arm/mach-prima2/rtciobrg.c:91:6: warning: symbol 'sirfsoc_rtc_iobrg_writel' was not declared. Should it be static?
