[ Upstream commit 3434341004a380f4e47c3a03d4320d43982162a0 ]
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).

commit 70ba2b0cbc54e0e2b7cb6d83d45fdefd9ca7e56e from
git@git.assembla.com:cavium/WindRiver.linux.git
This patch adds PCI device subsystem IDs of PTP on older and newer chips
and also registers PTP driver with them. Device id remains same for all
versions of chips but subsystem device id differenciates them.
