PATCH 1/1 regulator: tps65910: fix BUG_ON() shown with vrtc regulator

Fix BUG_ON() error if tps65910 VRTC regulator is used with out rdev->desc->volt_table data. Recent changes in regulator core driver which add support for "regulator_list_voltage_table" have BUG_ON() if regulator descriptor do not voltage table information. This patch adds the voltage table information to fix the issue.
