xen: cleanup unrealized flash devices
The generic pc_machine_initfn() calls pc_system_flash_create() which creates
'system.flash0' and 'system.flash1' devices. These devices are then realized
by pc_system_flash_map() which is called from pc_system_firmware_init() which
itself is called via pc_memory_init(). The latter however is not called when
xen_enable() is true and hence the following assertion fails:
qemu-system-i386: hw/core/qdev.c:439: qdev_assert_realized_properly:
Assertion `dev->realized' failed
These flash devices are unneeded when using Xen so this patch avoids the
assertion by simply removing them using pc_system_flash_cleanup_unused().
