Merge tag 'mvebu-soc-4.4-2' of git://git.infradead.org/linux-mvebu into next/soc

mvebu soc for 4.4 (part 2)

- Use mac_pton() helper in the oropn5x board instead of duplicating it
- Add the broken-idle option allowing to boot boards with a mistake in
  the hardware design

* tag 'mvebu-soc-4.4-2' of git://git.infradead.org/linux-mvebu:
  ARM: mvebu: add broken-idle option
  ARM: orion5x: use mac_pton() helper
