pwm: img: Fix PM reference leak in img_pwm_enable()
[ Upstream commit fde2529 ] pm_runtime_get_sync will increment pm usage counter even it failed. Forgetting to putting operation will result in reference leak here. Fix it by replacing it with pm_runtime_resume_and_get to keep usage counter balanced.
