Paul Cercueil Nov. 29, 2022, 7:17 p.m. UTC 
Use the new DEFINE_DRM_MODE_CONFIG_HELPER_PM_OPS() macro to create a
"struct dev_pm_ops" that can be used by this driver, instead of using
custom PM callbacks with the same behaviour.

v2: Use the DEFINE_DRM_MODE_CONFIG_HELPER_PM_OPS() macro instead of an
    exported dev_pm_ops.
