Shikra integrates two Qualcomm ETHQOS controllers based on the Synopsys
GMAC IP, similar to previous platforms.  Register qcom,shikra-ethqos
backed by a new shikra_data descriptor that enables the three NOC clocks
required for DMA memory access (axi-noc, pcie-tile-axi-noc, stmmaceth)
all at 120 MHz, and the 36-bit DMA address width.
