regulator: of: Add regulator desc param to of_get_regulator_init_data()
The of_get_regulator_init_data() function is used to extract the regulator
init_data but information on how to extract certain data is defined in the
static regulator descriptor (e.g: how to map the hardware operating modes).
Add a const struct regulator_desc * parameter to the function signature so
the parsing logic could use the information in the struct regulator_desc.
of_get_regulator_init_data() relies on of_get_regulation_constraints() to
actually extract the init_data so it has to pass the struct regulator_desc
but that is modified on a later patch.
