Getting the base address with outdated fdtdec_get_addr() API and further casting it to (void *) leads to next build warning on ARM64 platforms:
In function 'exynos_dwmci_get_config': warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] host->ioaddr = (void *)base;
Use livetree API instead (dev_read_addr_ptr()), which handles this correctly.
