[PATCH v2 07/26] drm: mxsfb: Define and use generic PM ops

[Paul Cercueil]

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.
