This is because ich9_lpc_sci_irq() returns -1 for reserved
(illegal) values, but ich9_lpc_pmbase_sci_update() considers
it valid and store it in a 8-bit unsigned type. Then the 255

Fix by simply ignoring the invalid access (and reporting it):

QEMU's kvmclock device is only created when KVM PV feature bits for
kvmclock (KVM_FEATURE_CLOCKSOURCE/KVM_FEATURE_CLOCKSOURCE2) are
exposed to the guest. With 'kvm=off' cpu flag the device is not
created and we don't call KVM_GET_CLOCK/KVM_SET_CLOCK upon migration.
It was reported that without these call at least Hyper-V TSC page
clocksouce (which can be enabled independently) gets broken after
migration.
Switch to creating kvmclock QEMU device unconditionally, it seems
to always make sense to call KVM_GET_CLOCK/KVM_SET_CLOCK on migration.
Use KVM_CAP_ADJUST_CLOCK check instead of CPUID feature bits.

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().
