dts: bindings: Document device tree bindings for Arm TRBE (2021-04-05 11:38:04 -0600)

----------------------------------------------------------------
Hi Marc,

As previously agreed, here are the changes to support CoreSight
ETE and TRBE components submitted here[1].

I draw your attention to these:

[PATCH v6 05/20] kvm: arm64: Handle access to TRFCR_EL1
[PATCH v6 06/20] kvm: arm64: Move SPE availability check to VCPU load
[PATCH v6 07/20] arm64: kvm: Enable access to TRBE support for host

They are KVM specific and will need an SoB tag.

Thanks,
Mathieu
