cdns2: Remove unused tracepoints

cdns2: Remove unused tracepoints

Tracepoints that are defined take up around 5K each, even if they are not
used. If they are defined and not used, then they waste memory for unused
code. Soon unused tracepoints will cause warnings.

Remove the unused tracepoints of the cdns2 subsystem. They are:

cdns2_ep0_enqueue
cdns2_ep0_set_config
cdns2_ep_queue
cdns2_iso_out_ep_disable
cdns2_lpm
cdns2_mapped_request
cdns2_map_request
cdns2_may_wakeup
