Documentation: ABI + trace: hisi_ptt: update paths to bus/event_source
To allow for assigning a suitable parent to the struct pmu device
update the documentation to describe the device via the event_source
bus where it will remain accessible.
For the ABI documention file also rename the file as it is named
after the path.
