What version are you building? In v5.0, PCI_KEYSTONE already selects
PCIE_DW_HOST:
$ git grep -A4 PCI_KEYSTONE v5.0:drivers/pci/controller/dwc/Kconfig | cat
v5.0:drivers/pci/controller/dwc/Kconfig:config PCI_KEYSTONE
v5.0:drivers/pci/controller/dwc/Kconfig- bool "TI Keystone PCIe controller"
v5.0:drivers/pci/controller/dwc/Kconfig- depends on ARCH_KEYSTONE || (ARM && COMPILE_TEST)
v5.0:drivers/pci/controller/dwc/Kconfig- depends on PCI_MSI_IRQ_DOMAIN
v5.0:drivers/pci/controller/dwc/Kconfig- select PCIE_DW_HOST
