Dominic Prinz 6e3c2d58e9 hw/acpi/ich9: Add periodic and swsmi timer
This patch implements the periodic and the swsmi ICH9 chipset timers. They are
especially useful when prototyping UEFI firmware (e.g. with EDK2's OVMF)
using QEMU.

For backwards compatibility, the compat properties "x-smi-swsmi-timer",
and "x-smi-periodic-timer" are introduced.

Additionally, writes to the SMI_STS register are enabled for the
corresponding two bits using a write mask to make future work easier.
