regulator: s5m8767: Modify parsing method of the voltage table of buck2/3/4
The s5m8767 regulator driver parse always the voltage table of buck2/3/4.
If gpio_dvs feature isn't used and dts haven't included the voltage table
of buck2/3/4, s5m8767 regulator driver return error and file probe state.
This patch check only voltage table of buck on s5m8767_pmic_dt_parse_pdata()
if buck[2-4]_gpiodvs is true.
