drivers: pci: imx: fix enumeration logic error
By default, the subordinate is set equally to the secondary bus (1) when the RC boots, and does not alter afterwards. This means that theoretically, the highest bus reachable downstream is bus 1. Force the PCIe RC subordinate to 0xff, otherwise no downstream devices will be detected behind bus 1 if the booting OS does not allow enumerating a higher busnr than the subordinate value of the primary bus.
