net phylib: force to wait for link ...

When starting a network device wait until the link is up. Otherwise
autobooting does not work with little timeout and several attempts
have to be made until the network is finally up.

clk: add always enabled clocks ...

Current barebox clk framework allow disable any clock
and there is no means to prevent that.

But there are the clocks that can't be disabled
by software at all.

This patch allow registration of a clock immune to clk_disable().

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.
