net: add driver for Synopsys Ethernet QoS device
This driver supports the Synopsys Designware Ethernet QoS (Quality of Service) a/k/a eqos IP block, which is a different design than the HW supported by the existing designware.c driver. The IP supports many options for bus type, clocking/reset structure, and feature list. This driver currently supports the specific configuration used in NVIDIA's Tegra186 chip, but should be extensible to other combinations quite easily, as explained in the source.
