regulator: s5m8767: Implement voltage setting for BUCK7/8 regulators
Voltage setting for BUCK7 and BUCK8 was not supported by s5m8767 driver.
If they were configured in DTS then the driver probing would fail with
EINVAL:
[ 0.288474] VCC_SUB_1.35V: failed to apply 1350000uV constraint
[ 0.288671] s5m8767-pmic s5m8767-pmic: regulator init failed for 35
[ 0.294931] s5m8767-pmic: probe of s5m8767-pmic failed with error -22
This patch adds support for BUCK7 and BUCK8 regulators using standard
regmap get/set voltage sel functions.
