This adds a driver for Alibaba CIPU PTP clock. The CIPU, an underlying
infrastructure of Alibaba Cloud, synchronizes time with atomic clocks
via the network and provides microsecond or sub-microsecond precision
timestamps for VMs and bare metals on cloud.

User space processes, such as chrony, running in VMs or on bare metals
can get the high precision time through the PTP device exposed by this
driver.

As mentioned on previous revisions this is a pure clock device which has
nothing to do with networking and PTP. There should be a separate class
for "hypervisor clocks", if not a common driver.
