[PATCH] fix i.MX51 babbage ethernet

This once again bends the init order to fit another board. This series
works over a number of shortcomings in barebox and devicetree support.
The problem here is that the Babbage ethernet phy needs vgen3 of the PMIC
enabled.

- We currently do not have proper regulator support for the mc13xxx,
  so we manipulate the PMIC registers directly from the board file. This
  has to happen before the ethernet phy is initialized. Once again
  we fiddle with the initcall order to make that sure. It can't be
  very long until we need some dependency mechanism for devices.
- Even if that is fixed the ethernet phy currently can't be described
  in the devicetree so we can't properly attach a regulator to it.

The following fixes ethernet support for the Babbage board which seems
to be broken for quite some time, at least when barebox is used as a
first stage loader.
