pwm: imx: Remove enabled field from struct imx_chip
We can test PWMF_ENABLED bit to know if pwm is enabled or not. Thus remove enabled field from struct imx_chip. Signed-off-by: Axel Lin <axel.lin@ingics.com> Acked-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de>
