Hardware needs a delay between setting an initial (non-zero) PWM and
enabling the backlight using GPIO. The post-pwm-on-delay-ms specifies
this delay in milli seconds. Hardware also needs a delay between disabing
the backlight using GPIO and setting PWM value to 0. The pwm-off-delay-ms
is this delay in milli seconds.

Changes since v5:
 - Add Acked-by: Thierry Reding [off-list ref]
 - CC DT mainling list (for some reason dropped at some point, my
   fault)
Changes since v4:
 - Rebase on top of mainline.
Changes since v3:
 - Replace us for ms.
 - Add Acked-by: Pavel Machek [off-list ref]
Changes since v2:
 - Use separate properties (Rob Herring)
Changes since v1:
 - As suggested by Daniel Thompson
   - Do not assume power-on delay and power-off delay will be the same
