See for example the 'Xen PC' machine configure its PCI bus calling pc_xen_hvm_init_pci(). There is no 'Xen Q35' machine declared. This code was probably added while introducing the Q35 machine, based on the existing PC machine (see commit df2d8b3ed4 "Introduce q35 pc based chipset emulator"). Remove the unreachable code to simplify this file.
