Support the new PHY_GENERIC device type, added in ESP-IDF v5.4.0 [1]. This PHY driver was added to ESP-IDF to support "generic"/oddball PHY LAN chips like the JL1101, which offer no features beyond the bare 802.3 PHY standard and don't actually need a chip-specific driver (see discussion at [2]).

This PHY driver was added to ESP-IDF to support "generic"/oddball PHY LAN chips like the JL1101, which offer no features beyond the bare 802.3 PHY standard and don't actually need a chip-specific driver (see discussion at [2]).
