it83xx: pwm: support PWM_CONFIG_DSLEEP config flag
With this change, we can keep a PWM channel active during
low-power idle (EC deep doze).
BRANCH=none
BUG=none
TEST=The pwm channel is function normally in deep doze mode.
And tested pwm frequency setting are:
300, 250, 200, 150, 100, 50, and 10 (Hz)
