While converting Mikrotik RB532 support to use device tree I stumbled
over the korina ethernet driver, which used way too many MIPS specific
hacks. This series cleans this all up and adds support for device tree.

Changes in v3:
  - fixed usage of of_get_mac_address for net-next
  - use readl_poll_timeout_atomic in mdio_wait
  - return -ETIMEDOUT, if mdio_wait fails
  - added DT binding and changed compatible name to idt,3243x-emac

Changes in v2:
  - added device tree support to get rid of idt_cpu_freq
  - fixed compile test on 64bit archs
  - fixed descriptor current address handling by storing/using mapped
    dma addresses (dma controller modifies current address)
