[PATCH net-next v3 1/5] dt-bindings: net: Add Maxio MAE0621A PHY

[Andre Przywara <andre.przywara@arm.com>]

From: Liu Changjie <liucj1228@outlook.com>

Document the MAE0621A PHY IDs (for the -Q2C and -Q3C variants) and their
optional 125 MHz CLKOUT setting. Boards which do not provide the property
retain the hardware strap or bootloader configuration.

Only the 125 MHz setting is exposed because it is the only setting
exercised on hardware.
