clocksource: samsung_pwm_timer: Handle suspend/resume correctly
Current suspend/resume handling of the driver was broken, because:
- periodic timer was being enabled in CLOCK_EVT_MODE_RESUME mode, which
does not seem to be correct behavior looking at other platforms,
- PWM divisors need to be restored, but they were not,
- clockevent interrupt mask needs to be restored, but it was not,
- clocksource was being restored in clockevent resume callback.
This patch fixes issues mentioned above, making suspend/resume handling
in the driver correct.
