74c654a852 net: cavium: Fix a bunch of kerneldoc parameter issues
Rename ptp to ptp_info.

Fix W=1 compile warnings (invalid kerneldoc):

aa3afccc9a net: cavium: Register driver with PCI subsys IDs
Across Cavium's ThunderX and Marvell's OcteonTx2 silicons
the PTP timestamping block's PCI device ID and vendor ID
have remained same but the HW architecture has changed.

Hence added PCI subsystem IDs to the device table to avoid
this driver from being probed on OcteonTx2 silicons.

3434341004 net: cavium: fix driver name
The driver name gets exposed in sysfs under /sys/bus/pci/drivers
so it should look like other devices. Change it to be common
format (instead of "Cavium PTP").

This is a trivial fix that was observed by accident because
Debian kernels were building this driver into kernel (bug).

ptp_clock_register never return NULL, so no need check this
in cavium_ptp_probe.

Use the module_pci_driver() macro to make the code simpler
by eliminating module_init and module_exit calls.

Prevent a kernel panic on reboot if ptp_clock is NULL by checking
the ptp pointer before using it.
