address.c has a same code block with fdt_address.c.
Remove a copy by moving the duplicated code block into of_private.h.

of_dump_addr() dumps __be32 array without conversion to CPU byte order
in advance, that will reduce log readability for little endian CPUs.
Fix by be32_to_cpu() conversion before dump.

FDT systems should never be relying on default cell sizes. It's been a
warning in dtc since 2007. The behavior here doesn't even match the
unflattened code which will walk the parent nodes looking for the cell
size properties (also deprecated). Furthermore, the FDT address
translation code is only used in one spot by SH and for earlycon which
was added 2014 and certainly isn't used on Powerpc systems.
Returning -1 values will result in an error message.

Clean-up all the DT printk functions to use common pr_fmt prefix.
Some print statements such as kmalloc errors were redundant, so just
drop those.

Cleanup the early DT/earlycon separation; remove the 'addr' parameter
from of_setup_earlycon() and get the uart phys addr directly with a
new wrapper function, of_flat_dt_translate_addr(). Limit
fdt_translate_address() to file scope.

Copy u-boot's FDT address translation code from common/fdt_support. This
code was originally based on the kernel's unflattened DT address parsing
code.
This commit can be reverted once relicensing of this code to GPLv2/BSD
is done and it is added to libfdt.
