lib: time: add weak timer_init() function
If timer_init() is made a weak stub function, then it allows us to remove several empty timer_init functions for those boards that already have a timer initialized when u-boot starts. Architectures that use the timer framework may also remove the need for timer.c. Signed-off-by: Darwin Rambo <drambo@broadcom.com> Reviewed-by: Tim Kryger <tim.kryger@linaro.org>
