regulator: core: Move of_find_regulator_by_node() to of_regulator.c
As of_find_regulator_by_node() is an of function it should be moved from core.c to of_regulator.c. It provides better separation of device tree functions from the core and allows other of_functions in of_regulator.c to resolve device_node to regulator_dev. This will be useful for implementation of parsing coupled regulators properties. Declare of_find_regulator_by_node() function in internal.h as well as regulator_class and dev_to_rdev(), as they are needed by of_find_regulator_by_node().
