[PATCH 02/16] coresight: etm: print what version of ETM/PTM is detected

[Mathieu Poirier]

From: Linus Walleij <linus.walleij at linaro.org>

Helpfully report a bit more about the hardware found in the
silicon when matching the AMBA device IDs by using the associated
.data pointer in the AMBA match.
