drivers: rkflash: nandc: use dev_pm_ops instead of legacy callback

Browse Source 
If the device has a 'power-domains' property that the power framework
prefer to use dev_pm_ops for suspend&resume. The legacy suspend & resume
callback for nandc driver would not be used.

Anyway, it's better use dev_pm_ops whether 'power-domains' is existent.
