habanalabs: define events to trace PCI LBW access 



There are cases where it may be useful to dump the whole LBW configs.
Yet, doing so while spamming the kernel log will probably shade other
important messages since the LBW access is done in sheer volume.
To answer this we add trace events for those too.
