add device_legacy_reset function to prepare for reset api change

Provide a temporary device_legacy_reset function doing what
device_reset does to prepare for the transition with Resettable
API.

All occurrence of device_reset in the code tree are also replaced
by device_legacy_reset.

The new resettable API has different prototype and semantics
(resetting child buses as well as the specified device). Subsequent
commits will make the changeover for each call site individually; once
that is complete device_legacy_reset() will be removed.
