Fugang Duan	94abdad697	net: ethernet: dwmac: add ethernet glue logic for NXP imx8 chip ... NXP imx8 family like imx8mp/imx8dxl chips support Synopsys MAC 5.10a IP. This patch adds settings for NXP imx8 glue layer: - clocks - dwmac address width - phy interface mode selection - adjust rgmii txclk rate v2: - adjust code sequences in order to have reverse christmas tree local variable ordering.
