pinctrl: nuvoton: Reduce use of OF-specific APIs

Browse Source 
Some drivers are using device property APIs along with OF-specific ones.
At the same time few of the latter can be converted to device property
calls. Reduce use of OF-specific APIs in order to bring a bit more consistency
into the drivers.
