[PATCH v2 1/2] arm64: dts: juno: Fix CoreSight support for Juno r1/r2 variants

[mike.leach@linaro.org (Mike Leach)]

The CoreSight support added for Juno is valid for only Juno r0.
The Juno r1 and r2 variants have additional components and alternative
connection routes between trace source and sinks.

The CoreSight infrastructure external to the Cortex-Axx clusters, has
been split into separate .dtsi include files for r0 and r1/r2 to correctly
represent these variations.
