core: demote a couple of messages from IMSG() to DMSG()

The first and and fourth lines in the boot sequence below are debug

No, it was added on purpose: afd58d7 ("Add one IMSG line before OP-TEE init message").

Ok, thanks for the link. Clear.
Instead, I think the hikey platform could:

Even proposal approved, maybe after 2.5.0. No hurry.
