This adds the device id mechanism to the i.MX fec driver and
uses it to determine the fec version. Also adds devicetree
probing support.

Adapt phylib from linux
switch all the driver to it
reimplement mii bus
This will allow to have
- phy drivers
- to only connect the phy at then opening of the device
- if the phy is not ready or not up fail on open
Same behaviour as in linux and will allow to share code and simplify porting.

The FSF address has changed in the past. Instead of updating it
each time the address changes, just drop it completely treewide.

remove double include, remove unused (and double in case of RCNTRL)
defines, sort the includes at least somewhat.

The i.MX28 comes with an extended ethernet controller (ENET/FEC) which
is backwards compatible to the FEC known from other i.MX CPUs. Add a few
adaptions to the existing driver to make it work with the MX28 FEC.

Some register bits are not defined in the IMX CPUs using this FEC (at least
I did not find anything about them in the related datasheets) and they will
get (partially) a new meaning in the i.MX28 CPU. So, removing them from the
source seems the best way to avoid any accidental usage on i.MX28.

This driver is not only used on i.MX27 but on i.MX35 and i.MX25, so
rename it to a more generic name
