-Names of regulators supported by S5M8767 device:
-	- LDOn
-		  - valid values for n are 1 to 28
-		  - Example: LDO1, LDO2, LDO28
-	- BUCKn
-		  - valid values for n are 1 to 9.
-		  - Example: BUCK1, BUCK2, BUCK9
-Note: The 'n' in LDOn and BUCKn represents the LDO or BUCK number
-as per the datasheet of device.

-Optional properties of the nodes under "regulators" sub-node:
- - op_mode: describes the different operating modes of the LDO's with
-            power mode change in SOC. The different possible values are,
-             0 - always off mode
-             1 - on in normal mode
-             2 - low power mode
