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.
