dm: regulator: add regulator command

This command is based on driver model regulator's API.
The user interface provides:
- list UCLASS regulator devices
- show or [set] operating regulator device
- print constraints info
- print operating status
- print/[set] voltage value [uV] (force)
- print/[set] current value [uA]
- print/[set] operating mode id
- enable the regulator output
- disable the regulator output

The 'force' option can be used for setting the value which exceeds
the constraints min/max limits.

+	  This command is based on driver model regulator's API.
+	  User interface features:
+	  - list               - list regulator devices
+	  - regulator dev <id> - show or [set] operating regulator device
+	  - regulator info     - print constraints info
+	  - regulator status   - print operating status
+	  - regulator value <val] <-f> - print/[set] voltage value [uV]
+	  - regulator current <val>    - print/[set] current value [uA]
+	  - regulator mode <id>        - print/[set] operating mode id
+	  - regulator enable           - enable the regulator output
+	  - regulator disable          - disable the regulator output
+
+	  The '-f' (force) option can be used for set the value which exceeds
+	  the limits, which are found in device-tree and are kept in regulator's
+	  uclass platdata structure.
