clocksource/drivers/timer-gx6605s: Fixup counter reload
When the timer counts to the upper limit, an overflow interrupt is generated, and the count is reset with the value in the TIME_INI register. But the software expects to start counting from 0 when the count overflows, so it forces TIME_INI to 0 to solve the potential interrupt storm problem.
