This series adds coresight support for SM8150 SoC and some coresight
DT changes to SC7180 SoC.

Patch 1 depends on coresight etm driver change:
 - https://git.linaro.org/kernel/coresight.git/commit/?h=next-v5.8-rc1&id=159e248e75b1b548276b6571d7740a35cab1f5be

Patch 3 depends on coresight replicator driver change:
 - https://git.linaro.org/kernel/coresight.git/commit/?h=next-v5.8-rc1&id=1b6cddfb7ebb5ed293124698f147e914b15315a1
 
Patch 4 depends on following coresight driver changes and SMMU DT node for SM8150
 - https://git.linaro.org/kernel/coresight.git/commit/?h=next-v5.8-rc1&id=159e248e75b1b548276b6571d7740a35cab1f5be
 - https://git.linaro.org/kernel/coresight.git/commit/?h=next-v5.8-rc1&id=1b6cddfb7ebb5ed293124698f147e914b15315a1
