net: stmmac: support max-speed device tree property
This patch adds support to "max-speed" property which is a standard Ethernet device tree property. max-speed specifies maximum speed (specified in megabits per second) supported the device. Depending on the clocking schemes some of the boards can only support few link speeds, so having a way to limit the link speed in the mac driver would allow such setups to work reliably. Without this patch there is no way to tell the driver to limit the link speed.
