Add Open Alliance spi protocol support.
Open Alliance is a chunk-based SPI protocol, based on sending
over SPI an ethernet frame divided in smaller chunks, using a
specific 32-bit header for each chunk transferred. All chunks
can be sent or received by a single dma transfer.
Default mode is set to Open Alliance SPI without protection,
since the adin2111 dev. board comes shipped this way.
Tested:
- Open Alliance SPI, no protection (default board shipped)
- Open Alliance SPI, protection
- Generic SPI, no crc
- Generic SPI, with crc8

After some debugging related to non-working "Generic SPI without CRC"
mode in eval_adin2111_ebz (CONFIG_ETH_ADIN2111_SPI_CFG0=n), noticed
that even after proper STATUS0 RESETC bit detection, registers,
for a certain period (some msecs) still reads as zero.
This patch fixes adin2111_await_device and with it the
"Generic SPI without CRC" mode.

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.

Adds initial ADIN2111 2-Port 10BASE-T1L (SPE)
switch support. Works over SPI.
The driver creates 2 interfaces, 1 per port (PHY).
Configures multicast and broadcast filters.
The same unicast is applied to both ports.
Supports:
- Link state detection
- CRC enable/disable
- Ports config set
- Ports ETH stats
Provides functions for MDIO driver.
