[PATCH 2/2] regulator: s5m8767: Fix driver probe fail on BUCK7/8 regulators

[Krzysztof Kozlowski]

The BUCK7 and BUCK8 were 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.
