pwm: Add PWM_CONFIG_DSLEEP config flag
Add PWM_CONFIG_DSLEEP PWM config flag, which can be set to keep a
channel active during low-power idle / deep sleep. Currently it's
supported by npcx and mec1322.
BUG=chrome-os-partner:52783
BRANCH=glados
TEST=Manual on chell w/ subsequent commit + CONFIG_LOW_POWER_S0. Verify
KB backlight does not flicker during idle.
