On platforms making a fair use of regulators, the dev_info() messages
coming from the device link function are a bit too verbose. The amount
of message will increase further with the clock framework joining the
device link party.

These messages looks valuable for people debugging device link related
issues, so dev_dbg() looks more appropriate than dev_info().
