[PATCH v10 10/10] arm64: dts: juno: Add Coresight CPU debug nodes

[Leo Yan]

From: Suzuki K Poulose <suzuki.poulose@xxxxxxx>

Add Coresight CPU debug nodes for Juno r0, r1 & r2. The CPU
debug areas are mapped at the same address for all revisions,
like the ETM, even though the CPUs have changed from r1 to r2.
