ARM/net: ixp4xx: Pass ethernet physical base as resource
In order to probe this ethernet interface from the device tree all physical MMIO regions must be passed as resources. Begin this rewrite by first passing the port base address as a resource for all platforms using this driver, remap it in the driver and avoid using any reference of the statically mapped virtual address in the driver.
