Enabling TPL (via DM or so) cannot be an optimal solutions as of now,
since if it continuously resetting we need to take boot switch based
on bootcount, ie possible with SPL and U-Boot proper now. Making a
boot switch to TPL might increase code size, so will check this
decision later based on the requirement.
