PCI: imx6: Delay link start until configfs 'start' written
According to Documentation/PCI/endpoint/pci-endpoint-cfs.rst, the Endpoint
controller (EPC) should only start the link when userspace writes '1' to
the '/sys/kernel/config/pci_ep/controllers/<EPC>/start' attribute, which
ultimately results in calling imx_pcie_start_link() via
pci_epc_start_store().
To align with the documented behavior, do not start the link automatically
when adding the EP controller.
Fixes: 75c2f26da03f ("PCI: imx6: Add i.MX PCIe EP mode support")
