drivers: ethernet: adin2111: add adin1110 support
Add support for ADIN1110 10BASE-T1L Ethernet MAC-PHY. The ADIN1110 is an ultra low power, single port, 10BASE-T1L transceiver design for industrial Ethernet applications and is com- pliant with the IEEE® 802.3cg-2019™ Ethernet standard for long reach, 10 Mbps single pair Ethernet (SPE). Featuring an integrated media access control (MAC) interface, the ADIN1110 enables direct connectivity with a variety of host controllers via a 4-wire serial peripheral interface (SPI). This SPI enables the use of lower power processors without an integrated MAC, which provides for the lowest overall system level power consumption. The SPI can be configured to use the Open Alliance SPI protocol or a generic SPI protocol.
