RDMA/ionic: map PHC state into user space
Enable user space applications to access the PHC state page when
firmware RDMA completion timestamp is supported.
This mapping allows user space to convert RDMA completion timestamps
to system wall time without kernel transitions, minimizing latency
overhead. Applications can directly read the PHC state through mmap,
enabling efficient timestamp correlation for precision timing
applications.
