-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.

-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

-             0 - always off mode
