[PATCH] ARM: prima2: make 'sirfsoc_rtc_iobrg_wait_sync' static

[Ben Dooks]

The 'sirfsoc_rtc_iobrg_wait_sync' function is not exported or used
outside of the rtciobrg.c fle, so fix the following warning by
making it static:

arch/arm/mach-prima2/rtciobrg.c:36:6: warning: symbol 'sirfsoc_rtc_iobrg_wait_sync' was not declared. Should it be static?
