ARM: OMAP: make ti81xx_rtc_hwmod static

The ti81xx_rtc_hwmod is not exported, or declared outside the file arch/arm/mach-omap2/omap_hwmod_81xx_data.c so make it static to avoid the following warning:

arch/arm/mach-omap2/omap_hwmod_81xx_data.c:246:19: warning: symbol 'ti81xx_rtc_hwmod' was not declared. Should it be static?
