Implement a suggestion by Scott Wood to make the /chosen handling fine
grained. Don't overwrite pre-existing properties on a per-property basis,
so if /chosen exists but a necessary /chosen/property doesn't, it gets
created. If a /chosen property exists, it is NOT overwritten unless the
"force" flag is true.

We use a combination of the serialN alias and CONFIG_CONS_INDEX to
determine which serial alias we should set linux,stdout-path to.

Added the following fdt fixup helpers:
* do_fixup_by_prop{_u32} - Find matching nodes by property name/value
* do_fixup_by_compat{_u32} - Find matching nodes by compat
The _u32 variants work the same only the property they are setting
is know to be a 32-bit integer instead of a byte buffer.

Moved the generic fixup handling code out of cpu/mpc5xxx and cpu/mpc8260
into common/fdt_support.c and renamed:
do_fixup() -> do_fixup_by_path()
do_fixup_u32() -> do_fixup_by_path_u32()

Removed:
fdt_node_is_compatible
fdt_find_node_by_type
fdt_find_compatible_node
To ease merge of newer libfdt as we aren't using them anywhere at this time.
Also moved fdt_find_and_setprop out of libfdt into fdt_support.c for the same
reason.

Previously ft_board_setup() was called by fdt_chosen() which was not
really correctly structured. This splits ft_board_setup() out by creating
a new fdt boardsetup command.
Fix a bug when parsing fdt set command values which have the square
bracket form [00 11 22 33] - the length was updated incorrectly in when
parsing that form.

The fdt_chosen() function was adding/seting some properties ad-hoc
improperly and duplicated (poorly) what was done in ft_board_setup()
Clean up long lines (setting properties, printing errors).

The new name matches more closely the kernel's name, which is also
a much better description.

Declare the variable fdt properly as extern.
Call the "set_fn" function pointer the "short way" without the full
dereferencing syntax.

Print more than the raw libfdt error message strings. This is especially
useful for cluing in the user when the bootm command aborts due to
blob problems.

What was suppose to be a stack variable was declared as a pointer,
overwriting random memory.
Also moved the libfdt.a requirement into the main Makefile. That is
The U-Boot Way.
In bootm, create the "/chosen" node only if it doesn't already exist
(better matches the previous behavior).
Update for proper reserved memory map handling for initrd.
