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.

This will ensure that we send an other packet only when the first one is send.

We never had interrupt support in barebox and we have no plans to
add interrupt support. Even if we do I doubt the current fragments
of irq support are helpful, so remove them.

To allow for some generic io accessors introduce io.h and use
this instead of asm/io.h throughout the tree.

this implementation is based on linux one (v2.6.35-rc5-76-gd0c6f62)
it will calculate all the clock dynamically instead of statictly
this will use also the new clock framework
it will also print the clock status after the console init

When operating in plain MII mode, the driver assumes the RMII bit not
set. Although this is the power on reset value, clearing this bit helps
when playing with different network setups.

The driver was not using the phy address supplied by the platform
data. With this patch the miiphy.address is set phy addr supplied
by the mac platform data.
