Subject: [PATCH -next] clocksource/drivers/arm_global_timer: Make symbol 'gt_clk_rate_change_nb' static

The sparse tool complains as follows:

drivers/clocksource/arm_global_timer.c:54:23: warning:
 symbol 'gt_clk_rate_change_nb' was not declared. Should it be static?

This symbol is not used outside of arm_global_timer.c, so marks it static.
