ptp: ptp_vmclock: add 'VMCLOCK' to ACPI device match

Browse source 
As we finalised the spec, we spotted that vmgenid actually says that the
_HID is supposed to be hypervisor-specific. Although in the 13 years
since the original vmgenid doc was published, nobody seems to have cared
about using _HID to distinguish between implementations on different
hypervisors, and we only ever use the _CID.

For consistency, match the _CID of "VMCLOCK" too.
