[PATCH] configure environment from devicetree

[Sascha Hauer]

This adds a driver which allows to configure the place where the
environment is stored from devicetree. The changes to the last
series I posted are:

- drop barebox specific partition driver and instead expect the
  partition nodes directly under the devicenode for the physical
  device.
- use /chosen instead of /chosen/barebox for barebox specific
  configuration drivers
