From: Icenowy Zheng <redacted> Allwinner A64 has a SRAM controller, and in the device tree currently we have a syscon node to enable EMAC driver to access the EMAC clock register. As SRAM controller driver can now export regmap for this register, replace the syscon node to the SRAM controller device node, and let EMAC driver to acquire its EMAC clock regmap.
