omap24xx: fix 'reset_timer_masked' declaration error

Commit 17659d7 "Timer: Remove reset_timer_masked()" introduced a
static declaration for reset_timer_masked() which causes build errors:

timer.c:45: error: static declaration of 'reset_timer_masked' follows non-static declaration
include/asm/u-boot-arm.h:70: error: previous declaration of 'reset_timer_masked' was here
