Subject: [PATCH net-next 1/2] ARM: dts: socfpga: DTS updates for stmmac driver

This change adds a parameter for the Synopsys 10/100/1000
stmmac Ethernet driver to configure the maximum MTU supported
by the EMAC instance. Synopsys allows the FIFO sizes to
be configured when the cores are built for a particular
device, but do not provide a way for the driver to read
information from the device about the maximum MTU size
supported as limited by the device's FIFO size.

This patch has been tested with changes being submitted
seperately for the Synopsys 10/100/1000 stmmac driver.
