clocksource: dw_apb_timer_of: Fix read_sched_clock
The read_sched_clock should return the ~value because the clock is a countdown implementation. read_sched_clock() should be the same as __apbt_read_clocksource(). Signed-off-by: Dinh Nguyen <dinguyen@altera.com> Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org>
