The j721e driver has a single platform driver that can be built-in or a loadable module, but it calls two separate backend drivers depending on whether it is a host or endpoint. If the two modes are not the same, we can end up with a situation where the built-in pci-j721e driver tries to call the modular host or endpoint driver, which causes a link failure: ld.lld-21: error: undefined symbol: cdns_pcie_ep_setup >>> referenced by pci-j721e.c >>> drivers/pci/controller/cadence/pci-j721e.o:(j721e_pcie_probe) in archive vmlinux.a ld.lld-21: error: undefined symbol: cdns_pcie_host_setup >>> referenced by pci-j721e.c >>> drivers/pci/controller/cadence/pci-j721e.o:(j721e_pcie_probe) in archive vmlinux.a Rework the dependencies so that the 'select' is done by the common Kconfig symbol, based on which of the two are enabled. Effectively this means that having one built-in makes the other either built-in or disabled, but all configurations will now build.
