Document the "op_mode" properties parsed from DTS by s2mps11 driver.
S2MPS11/S2MPS14 regulators support different modes of operation:
- Always off;
- On/Off controlled by pin/GPIO (PWREN/LDOEN/EMMCEN);
- Always on;
This is very similar to S5M8767 regulator driver which also supports
opmodes (although S5M8767 have also low-power mode).

The regulator constraints inside the regulator nodes use the standard regulator
bindings which are documented elsewhere.
+On S2MPS14 chipset the driver additionally supports "op_mode" properties for
+each regulator.
+ - op_mode: describes the different operating modes of the regulators with
+ power mode change in SOC. The different possible values are,
+ 0 - always off mode
+ 1 - on in normal mode
+ 3 - suspend mode
+ (NOTE: value of 2 is reserved)

The following are the names of the regulators that the s2mps11 pmic block
supports. Note: The 'n' in LDOn and BUCKn represents the LDO or BUCK number
as per the datasheet of s2mps11.
