[U-Boot] [PATCH] net/designware: make driver compatible with data cache

Up until now this driver only worked with data cache disabled. To make it work with enabled data cache following changes were required: * Implement all accesses to shared structures between CPU and GMAC via uncached reads/writes (readl/writel). * Flush cache for data passed from CPU to GMAC *
