I'm taking care of this now, but JFYI, this is actually a tricky
conversion where the "hack print" tool I've posted before is required,
along with running it with and without CONFIG_SPL_BUILD defined.  At
issue here is that a number of platforms play games with only setting
CONFIG_POWER in SPL, really but moveconfig.py doesn't catch it.  You can
see this with the buildman size/bloat functions and that main U-Boot
nows includes drivers/power/power_core.c and its non-DM non-configurable
pmic cmd.
