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.
