coresight: Updates for v6.5

CoreSight and hwtracing subsystem updates for v6.5 includes:
 
  - Fixes to the CTI module reference leaks. This involves,
    redesign of how the helper devices are tracked and CTI
    devices have been converted to helper devices.
  - Fix removal of the trctraceidr file from sysfs for ETMs.
  - Match all ETMv4 instances based on the ETMv4 architected
    registers and the CoreSight Component ID (CID), than having
    to add individual PIDs for CPUs.
  - Add support for Dummy CoreSight source and sink drivers.
  - Add James Clark as Reviewer for the CoreSight kernel drivers
  - Fixes to HiSilicon PCIe Tune and Trace Device driver
