pmdomain: rockchip: add regulator dependency

When CONFIG_REGULATOR is disabled, this pmdomain driver fails to build:

drivers/pmdomain/rockchip/pm-domains.c:653:30: error: implicit declaration of function 'devm_of_regulator_get'; did you mean 'devm_regulator_get'? [-Wimplicit-function-declaration]
  653 |                 pd->supply = devm_of_regulator_get(pmu->dev, pd->node, "domain");
      |                              ^~~~~~~~~~~~~~~~~~~~~
      |                              devm_regulator_get
drivers/pmdomain/rockchip/pm-domains.c:653:28: error: assignment to 'struct regulator *' from 'int' makes pointer from integer without a cast [-Wint-conversion]
  653 |                 pd->supply = devm_of_regulator_get(pmu->dev, pd->node, "domain");
      |                            ^

Add a Kconfig dependency.
