[PATCH] clocksource/drivers/digicolor: fix warning of non-static function

[ben.dooks@codethink.co.uk (Ben Dooks)]

Change the dc_timer function to be static as it is not used outside
this driver. This fixes the following warning:

drivers/clocksource/timer-digicolor.c:66:24: warning: symbol 'dc_timer' was not declared. Should it be static?
