net: stmmac glue layer for Amlogic Meson SoCs

the Ethernet controller available in Amlogic Meson6 and Meson8 SoCs is
a Synopsys DesignWare MAC IP core, already supported by the stmmac
driver.

These patches add a glue layer to the driver for the platform-specific
settings required by the Amlogic variant.

This has been tested on a Amlogic S802 device with the initial Meson
support submitted by Carlo Caione [1].
