reset: sti: Use devm_kcalloc() in syscfg_reset_controller_register()
* 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_kcalloc".
* Replace the specification of a data structure by a pointer dereference
to make the corresponding size determination a bit safer according to
the Linux coding style convention.
* Delete the local variable "size" which became unnecessary with
this refactoring.
