ptp_ocp is a real PCIe device with an atomic clock. mhi_phc is some
qualcomm fw-defined thing, so more closely mapping what you're doing.
ptp_ocp should probably stay under netdev, we maintain DPLL drivers,
too. Main thing we/I don't want to deal with is all the corporate NIH
virtualization excreta.
