mvebu: LS421DE: dts file improvements

- Delete useless HDD presence inputs: they aren't buttons, and probably
  they are outputs in the stock firmware.
- Change the Function Button keycode: the current one isn't mapped by
  the kernel module.
- Use the recommended property names for the ethernet stuff.
- Add missing i2c pinmux.
- Minor cosmetic changes.
