clk: initial common clk support ...

This adds barebox common clk support loosely based on the Kernel common
clk support. differences are:

- barebox does not need prepare/unprepare
- no parent rate propagation for set_rate
- struct clk is not really encapsulated from the drivers

Along with the clk support we have support for some basic clk building
blocks:

- clk-fixed
- clk-fixed-factor
- clk-mux
- clk-divider

clk-fixed and clk-fixed-factor are completely generic, clk-mux and clk-divider
are currently the way i.MX muxes/dividers are implemented.

clk clkdev: Add clkdev matching based on physbase ...

Most clock/device associations can be done based on the physical
base address of the corresponding device. So instead of depending
on string matching add an optional possibility to associate a clock
lookups with physical addresses. This also has the advantage that
the lookups for devicetree based devices can be identical to the
platform based devices.

net: introduce phylib ...

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.
