The SoCFPGA currently has all clocks described in the devicetree which
makes common clock support a straight forward task.

This patch provides a global cleanup barebox Kconfig files. This includes
replacing spaces to tabs, formatting in accordance format.
No functional changes.

So that drivers can use clk_* functions without having to ifdef
them away.

Barebox not contain symbol HAVE_CLK, so remove all references to it.

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.

as refer in this patch "arm & sh: factorised duplicated clkdev.c"
factorise some generic infrastructure to assist looking up struct clks
for the ARM & SH architecture.
as the code is identical at 99% in linux
move it also as preparing for the SH adding
