cxl/pci: Drop the parameter is_port of cxl_gpf_get_dvsec()

The first parameter of cxl_gpf_get_dvsec() is a struct device, can be
used to distinguish if the device is a cxl dport or a cxl pci device by
checking the PCIe type of it, so the parameter is_port is unnecessary
to cxl_gpf_get_dvsec(), using parameter struct device is enough.
