It can be hard for people not familiar with the CoreSight IP blocks
to make sense of the acronyms found in the current bindings. As such
this patch expands each acronym in the hope of providing a better
description of the IP block they represent.

Thanks for the update. One minor comment below.

Is it worth an explicit mention about this, something like :
"We don't need special bindings for the mode (e.g, ETB, ETF or ETR) in
which the Coresight TMC is configured".

Either way, looks good to me.
