Subject: [PATCH] esp_eth: rework KSZ80xx implementation and add more KSZ80xx
 PHYs

* add support for KSZ8001, KSZ8021, KSZ8031, KSZ8051 and KSZ8061
* remove duplicate code
* simplify architecture to make the code base extensible (for future work)


* Original commit: espressif/esp-idf@3fb83f2866f266209e3aaed0c80df952b8d82b91
