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.
