From: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com>

commit fd8d8e63467c922be9ae4452cca2980d473477d9 upstream.

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.

Fixes: 01fb4d3c39d3 ("PM / OPP: Parse 'opp-<prop>-<name> 'bindings")
