ARM: omap2: fix missing tick_broadcast() prototype
omap2 contains a hack to define tick_broadcast() on non-SMP
configurations in place of the normal SMP definition. This one
causes a warning because of a missing prototype:
arch/arm/mach-omap2/board-generic.c:44:6: error: no previous prototype for 'tick_broadcast'
Make sure to always include the header with the declaration.
