This includes:
* support allocation of CQ with the TIMESTAMP_COMPLETION creation flag.
* add timestamp_mask and hca_core_clock to query_device, reporting the
number of supported timestamp bits (mask) and the hca_core_clock frequency.
* return hca core clock's offset in query_device vendor's data,
this is needed in order to read the HCA's core clock.
