The check is wrong since it would have to check whether the
new iomem region overlaps with an existing region. Checking
for the base address only is not enough.
Currently this is not possible because every device conflicts
with the top iomem region which covers the whole address space.
This at least fixes the regression that devices whose memory region
begins at 0x0 can no longer be succesfully registered.

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.

This currently depends on a safe read_byte (always) and read_buf

is not something that generally works. For this reason the existence
of the set_buswidth callback is used to determine whether we are
