When a memory bank is already registered, return an error code
instead of throwing a bug. This can happen if a board has registered
a memory bank and the same bank is then probed from the devicetree.

of_alias_get_id() returns the number of the gpio bank, so we have
to multiply with 32 to get the gpio base.

The _send function should not return the length

We called create_sections with 4096MB as size argument, but create_sections
expected the argument in bytes, so create sections was completely optimized
away due to the size >>= 20. This patch changes the size argument to be in
megabytes and adjusts map_cachable to pass the argument in megabytes.

We can't do anything useful in the error function, so we just hang.
This has the advantage that at least when a JTAG debugger is connected
we can see what happens. Otherwise the code just jumps to NULL in case
of an error.

- The i.MX1 timer does not have IPG clock as source, so rename

- for the i.MX31 timer we want to use the per clock, not the ipg
clock.

The old clock support is now unused. Remove it. The former i.MX clko
command is superseeded by generic clock manipulation commands.

This adds some basic commands to manupulate clocks on the command
line. Right now we have:
- clk_set_parent
- clk_set_rate
- clk_enable
- clk_disable
- clk_dump
The commands work based on the clock name, otherwise they behave like
the Linux Kernel C functions. clk_dump will dump the clocktree to the
console.

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.

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.
