drivers: i2c: i2c_dw: Add capability for handling reset device

Reset the device on initializing if reset-node is available in dts.
`snps,desingware-i2c` does not define reset-node itself.
Add more of an element that inherits `reset-device.yaml` to
the `compatible` section to allow defining the reset-node
for using this feature.

For example.

```
compatible = "reset-device-inherit-node", "snps,designware-i2c";
```
