Merge patch series "Complete decoupling of bootm logic from commands"

Simon Glass <sjg@chromium.org> says:

This series continues refactoring the bootm code to allow it to be used
with CONFIG_COMMAND disabled. The OS-handling code is refactored and
a new bootm_run() function is created to run through the bootm stages.
This completes the work.

A booti_go() function is created also, in case it proves useful, but at
last for now standard boot does not use this.

This is cmdd (part d of CMDLINE refactoring)
It depends on dm/bootstda-working
which depends on dm/cmdc-working
