regulator: qcom_smd: add list_voltage callback

commit a8a47540ebe32f1733eebc3e5699af580ceaa3f5 upstream.

This patch adds support to list_voltage callback, so that consumers
like mmc core, can get information of supported voltage range.

Without this patch there is no way for mmc core to know this voltage range.
