[PATCH 2/2] regulator: s2mps11: Use devm_kmalloc_array() in s2mps11_pmic_probe()

A multiplication for the size determination of a memory allocation
indicated that an array data structure should be processed.
Thus use the corresponding function "devm_kmalloc_array".
This issue was detected by using the Coccinelle software.
