i2c: sun6i_p2wi: Add support for DM clocks and resets
Currently, clock/reset setup for this device is handled by a
platform-specific function and is intermixed with non-DM pinctrl
setup. Use the devicetree to get clocks/resets, which disentagles
it from the pinctrl setup in preparation for moving to DM_PINCTRL.
