[PATCH 4/7] reset: Supply *_shared variant calls when using *_optional APIs

[Lee Jones]

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.
