Manjunath Kondaiah G 04aeae7779 OMAP2plus: Fix static function warnings
This patch fixes sparse warnings due non declarations of static functions.

arch/arm/mach-omap2/timer-gp.c:115:12: warning: symbol 'omap2_gp_clockevent_set_gptimer' was not declared. Should it be static?
arch/arm/mach-omap2/powerdomain.c:993:5: warning: symbol 'pwrdm_set_lowpwrstchange' was not declared. Should it be static?
arch/arm/mach-omap2/board-flash.c:141:8: warning: symbol 'board_nand_init' was not declared. Should it be static?
arch/arm/mach-omap2/board-n8x0.c:416:6: warning: symbol 'n8x0_mmc_slot1_cover_handler' was not declared. Should it be static?
arch/arm/mach-omap2/board-n8x0.c:544:13: warning: symbol 'n8x0_mmc_init' was not declared. Should it be static?
