pcie-kirin uses regmaps, and needs to pull them in; otherwise, with
CONFIG_PCIE_KIRIN=y and without CONFIG_REGMAP:

drivers/pci/controller/dwc/pcie-kirin.c:359:21: error: variable ‘pcie_kirin_regmap_conf’ has initializer but incomplete type
  359 | static const struct regmap_config pcie_kirin_regmap_conf = {

Similarly, without CONFIG_REGMAP_MMIO, pcie-kirin produces a linker
failure looking for __devm_regmap_init_mmio_clk.

Applied to controller/kirin, thanks!
