regulator: Move OF_ API declarations/definitions outside CONFIG_REGULATOR

Since these are hidden inside CONFIG_REGULATOR, building the consumer
drivers without CONFIG_REGULATOR will result in the following build error:

>> drivers/pci/pwrctrl/slot.c:39:15: error: implicit declaration of
function 'of_regulator_bulk_get_all'; did you mean 'regulator_bulk_get'?
[-Werror=implicit-function-declaration]
      39 |         ret = of_regulator_bulk_get_all(dev, dev_of_node(dev),
         |               ^~~~~~~~~~~~~~~~~~~~~~~~~
         |               regulator_bulk_get
   cc1: some warnings being treated as errors

This also removes the duplicated definitions that were possibly added to
fix the build issues.
