Jiawen Wu 2f8d1ed793 i2c: designware: Add driver support for Wangxun 10Gb NIC
Wangxun 10Gb ethernet chip is connected to Designware I2C, to communicate
with SFP.

Introduce the property "wx,i2c-snps-model" to match device data for Wangxun
in software node case. Since IO resource was mapped on the ethernet driver,
add a model quirk to get regmap from parent device.

The exists IP limitations are dealt as workarounds:
- IP does not support interrupt mode, it works on polling mode.
- Additionally set FIFO depth address the chip issue.
