[PATCH v2 00/13] prepare Protonic board code for mainline

[Oleksij Rempel]

changes v2:
- add power init support for KvG boards
- spell fixes
- do not print error on probe exit
- add of_console_get_by_alias() helper
- free requested gpio array
- exit fec init only in case of PROBE_DEFERED

This patch series is a preparation and actual Protonic board code.
Following changes was made in the main code:
- register DT root node as device to make it possible to loade board
  code as usual driver
- provide helpers to read ethernet mac from nvmem cell register in a
  devicetree.
- provide barebox-serial driver which should be a nvmem cell consumer
  and
  serial-number DT property provider.
- provide gpio helper to read gpio based board revision.
