Jian Jun Chen 31b8b698ce hv: TLFS: Add tsc_offset support for reference time ... TLFS spec defines that when a VM is created, the value of HV_X64_MSR_TIME_REF_COUNT is set to zero. Now tsc_offset is not supported properly, so guest get a drifted reference time. This patch implements tsc_offset. tsc_scale and tsc_offset are calculated when a VM is launched and are saved in struct acrn_hyperv of struct acrn_vm.
