    Adds PHY driver. Works via MDIO API and
exposed ADIN2111 MDIO Clause 45
functions.

Link status detection is triggered by
ADIN2111 driver within offloaded IRQ
handler.

Supports:
  - LED0, LED1 enable/disable
  - Fatal HW error detection
  - AN 2.4V tx mode enable/disable

The initialization order is important.
PHY 2 must be initialized after PHY1.
Therefore, it shall be defined after the 1st one
in the devicetree.
