Liran Alon d6048bfd12 hw/i386/vmport: Add support for CMD_GETHZ
This command returns to guest information on LAPIC bus frequency and TSC
frequency.

One can see how this interface is used by Linux vmware_platform_setup()
introduced in Linux commit 88b094fb8d4f ("x86: Hypervisor detection and
get tsc_freq from hypervisor").
