Add support for the MaxLinear MxL86110 Gigabit Ethernet PHY, a low-power,
cost-optimized transceiver supporting 10/100/1000 Mbps over twisted-pair
copper, compliant with IEEE 802.3.

The driver implements basic features such as:
- Device initialization
- RGMII interface timing configuration
- Wake-on-LAN support
- LED initialization and control via /sys/class/leds

This driver has been tested on multiple Variscite boards, including:
- VAR-SOM-MX93 (i.MX93)
- VAR-SOM-MX8M-PLUS (i.MX8MP)

net: phy: Add support for Aeonsemi AS21xxx PHYs

Add support for Aeonsemi AS21xxx 10G C45 PHYs. These PHYs integrate
an IPC to setup some configuration and require special handling to
sync with the parity bit. The parity bit is a way the IPC use to
follow correct order of command sent.

Supported PHYs AS21011JB1, AS21011PB1, AS21010JB1, AS21010PB1,
AS21511JB1, AS21511PB1, AS21510JB1, AS21510PB1, AS21210JB1,
AS21210PB1 that all register with the PHY ID 0x7500 0x7510
before the firmware is loaded.

They all support up to 5 LEDs with various HW mode supported.

While implementing it was found some strange coincidence with using the
same logic for implementing C22 in MMD regs in Broadcom PHYs.

For reference here the AS21xxx PHY name logic:

AS21x1xxB1

The module init / exit functions from mdio_bus.c no longer have to be
