[U-Boot] [PATCH] power: extend prefix match to regulator-name property

[Felix Brack]

This patch extends pmic_bind_children prefix matching. In addition to
the node name the property regulator-name is used while trying to match
prefixes. This allows assigning different drivers to regulator nodes
named regulator at 1 and regulator at 10 for example.
