This series adds the CoreSight debug and trace subsystem for the
Qualcomm Shikra SoC.

The first patch adds a fallback compatible for the Shikra CTCU (CoreSight
Trace Control Unit). The CTCU on Shikra shares the same configuration as
the one on SA8775p, so "qcom,shikra-ctcu" falls back to the existing
"qcom,sa8775p-ctcu" compatible.

The second patch adds the DT nodes describing the CoreSight topology on
Shikra, including the funnels, replicators, TMC sinks (ETR/ETF), STM,
per-core ETMs, CTIs, and the TPDM/TPDA trace collection blocks, along
with the CTCU and the dummy source/sink endpoints that model external
trace sources and the EUD sink.
