Created a bootm_start() that handles the parsing and detection of all
the images that will be used by the bootm command (OS, ramdisk, fdt).
As part of this we now tract all the relevant image offsets in the
bootm_headers_t struct. This will allow us to have all the needed
state for future sub-commands and lets us reduce a bit of arch
specific code on SPARC.
Created a bootm_load_os() that deals with decompression and loading
the OS image.

To allow for persistent state between future bootm subcommands we
need the lmb to exist in a global state.
Moving it into the bootm_headers_t allows us to do that.

Move determing if we have a ramdisk and where its located into the
common code. Keep track of the ramdisk start and end in the
bootm_headers_t image struct.

Move entry point code out of each arch and into common code.
Keep the entry point in the bootm_headers_t images struct.

The autostart revert caused a bit of duplicated code as well as
code that was using images->autostart that needs to get removed so
we can build again.
