coresight: tmc: implementing TMC-ETR AUX space API

This patch implement the AUX area interfaces required to
use the TMC (configured as an ETR) from the Perf sub-system.

The ETR is configured to work with contiguous memory only.
Although not optimal, it allows the IP block to be used
while the scatter-gather mode of operation is being worked
on.

The heuristic is heavily borrowed from the ETB10 and TMC-ETF
implementation.
