[PATCH] clocksource/drivers/timer-gx6605s: Fixup counter reload

[guoren]

From: Guo Ren <guoren@xxxxxxxxxxxxxxxxx>

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.
