This adds gmac1 controller support for the Allwinner sun55i (A523/A527/T527) platform. Unlike the gmac0 controller which uses the older sun8i-emac IP, gmac1 utilizes the Synopsys DesignWare Ethernet QOS IP block.
In addition to porting the DWC_ETH_QOS_SUNXI driver from upstream Linux, this series also introduces support for relevant dependencies, including clocks, pinctrl, and syscon required to make the controller fully functional. This was tested on the Radxa Cubie A5E board, and the relevant options are enabled as well.
