ARM: EXYNOS: fix thermal throttle on TMU_STATUS_THROTTLED

With TMU state changed from TMU_STATUS_NORMAL to TMU_STATUS_THROTTLED,
when the function exynos_thermal_throttle is called once, TMU state is
back to TMU_STATUS_NORMAL immediately. This leads not to function
thermal throttling as expected.
This patch fixes thermal throttle on TMU_STATUS_THROTTLED.
