Revert "net fec: connect phy at probe time" ...

While this makes sure that the phy fixups are applied even if
networking is not used on i.MX6, this patch due to latest phy
changes causes the startup of barebox delayed until we have a
link on the i.MX fec. Revert it for now and look for a better
solution later.

This reverts commit 3a17af3.

net fec: call fec_init at probe time ...

fec_init() initializes some bits important for phy access, so do
this before the mdiobus is registered. This fixes mdiobus support
on i.MX28 boards in RMII mode.

net fec: connect phy at probe time ...

Several i.MX boards (all i.MX6 boards) need to do some adjustments
to phy registers. If barebox itself does not use network, networking
won't work in the kernel if the kernel does not have the fixups. Connect
the phy at probe time so that these tweaks are done during probe so that
the kernel works without phy register tweaks. Also this has the effect
that the phy device is present and introspectable without doing fake
network transfers beforehand.

net: introduce phylib ...

Adapt phylib from linux

switch all the driver to it
reimplement mii bus

This will allow to have

 - 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.
