The common bootm code used to load uImage contents to SDRAM
before calling into the handlers if possible. This makes the
handlers complicated since they have to handle many cases. Instead,
introduce a helper to load the os after the handlers have figured
out a good load address.

This adds support for checking the bootm command without actually booting.

We used to use struct image_data as the central data structure for bootm and
also as the input data structure. This makes it unclear which of the fields
are actually input data. This patch creates a struct bootm_data which is
exclusively used for input data to make usage clearer.
Also it moves the dispatching of multifile uImage pathnames to the core bootm
code so that the core code gets more flexible and the command code simpler.

The globalvars should be available even if the bootm command
is not directly present.

getenv_loadaddr may be used by other code, so move it
from command/ to common/

data->of_root_node may be allocated from of of_unflatten_dtb.
Free it in this case.

Much of the bootm code is implemented in the command itself. Move
it to a common place to be able to call it from C aswell.
