In the Linux kernel driver, all information related to LDO and BUCK
regulators are stored in descriptive arrays. This also allows multiple
variants to be supported by the same driver.
Define a struct sec_regulator_desc which holds all values required by a
regulator. Create an array of said struct containing all regulators. The
descriptors are designed to follow a style similar to what's seen in the
Linux driver, so comparing one with the other is simple.
In functions such as s2mps11_{buck,ldo}_{val,mode} these values are to
be used, make necessary modifications to pull them from the descriptors.
Since multiple variants have varying descriptors, select them from
within a switch-case block.
Functions s2mps11_{buck,ldo}_{volt2hex,hex2volt} and arrays
s2mps11_buck_{ctrl,out} are phased out as the calculations are now
hardcoded in descriptors, thusly, it reduces clutter and enhances
readability.
Two macros in s2mps11.h, S2MPS11_LDO_NUM and S2MPS11_BUCK_NUM are
removed as they are no longer being used.
