NULL pointers should be treated as dummy clocks as done in the kernel.
Using a not fully filled in clk * array for of_clk_add_provider may result
in NULL clks. When these are passed into the clk framework we should not
crash.

This board was broken since the switch to use upstream DTs with v2014.07.
Fix it up by including the right upstream DT and delete some now
unneeded files.

The original script was written by Grant Likely <grant.likely@linaro.org>.
The version for barebox also imports some libfdt sources, so that we are
able to compile the fdtget host tool. Also remove the unused non-kconfig
makefiles.

of_alias_get assumed that a DT path is always the full node path,
whic is not necessarily the case, as there are other valid path
descriptions. All of them are handled by of_find_node_by_path.
As there is already a preparsed list with all DT aliases that handles
this case properly we can simply reuse that one.

The environment on the QSB is configured via devicetree, but in
the code there's also a /dev/env0 registered which is unused. Remove
it.

Otherwise the write would be skipped if we are already running on the main CPU
cluster. In practice this means that a second stage barebox will reuse the DT
of the first stage, instead of using it's own.

The cache should be invalidated when transfering ownership of a buffer
to the device. Otherwise the writeback of dirty cache lines can

reset_source_init used to set the reset source to unknown in a
coredevice_initcall. This means if reset_source_set() has been called
earlier the value would have been overwritten. Fix this by calling
globalvar_add_simple() each time reset_source_set() is called.
