[PATCH 1/6] hw/pci-bridge/cxl_root_port: Provide x-speed and x-width properties.

[Jonathan Cameron <Jonathan.Cameron@huawei.com>]

Approach copied from gen_pcie_root_port.c
Previously the link defaulted to a maximum of 2.5GT/s and 1x.  Enable setting
it's maximum values.  The actual value after 'training' will depend on the
downstream device configuration.
