reset: Supply *_shared variant calls when using *_optional APIs
Consumers need to be able to specify whether they are requesting an
'exclusive' or 'shared' reset line no matter which API (of_*, devm_*,
etc) they are using. This change allows users of the optional_* API
in particular to specify that their request is for a 'shared' line.
