Introduce MDIO bus frequency support. This way the board can have a
faster (or maybe slower) bus frequency than the hardware default.

changes since v1:
 - fail probe if clock-frequency is set, but not clock is given
 - rename clk_freq to bus_freq
 - add maxItems to interrupts property
 - put compatible and reg first in the example

Michael Walle (3):
  dt-bindings: net: convert mscc-miim to YAML format
  dt-bindings: net: mscc-miim: add clock and clock-frequency
  net: phy: mscc-miim: add support to set MDIO bus frequency
