[PATCH v2] PM / OPP: Fix parsing of opp-microvolt and opp-microamp properties

[Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com>]

Commit 01fb4d3c39d3 ("PM / OPP: Parse 'opp-<prop>-<name>'
bindings") broke support for parsing standard opp-microvolt and
opp-microamp properties.  Fix it by setting 'name' string to
proper value for !prop cases.
