[PATCH 1/5] hw/i386/q35: Remove unreachable Xen code on Q35 machine

[Philippe Mathieu-Daudé <philmd@xxxxxxxxxx>]

Xen accelerator requires specific changes to a machine to be able
to use it. 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.
