sh: Fixed the TMU0 reload value on resume
This patch fixes the TMU0 interrupt frequency on suspend/resume. During the resume the kernel reprograms the TMU0.ClockEvent mode but if the mode is periodic than the TMU0.TCOR is updated with a random wrong value without taking care latest valid saved value. There was no problem with No_HZ system where TMU0.TCOR isn't used. Signed-off-by: Francesco M.
