[PATCH v17 08/10] coresight: Add CORESIGHT_DEVID2 to linux/coresight.h

[Songwei Chai <songwei.chai@oss.qualcomm.com>]

CORESIGHT_DEVID2 lives at a fixed, architecturally-defined offset
(0xfc0) within the generic CoreSight management register block,
immediately preceding CORESIGHT_DEVID (0xfc8). Components outside
drivers/hwtracing/coresight/ that follow the same register convention
(e.g. the Qualcomm TGU, which uses it to detect its timer/counter
capabilities) need to read it too.

Add it to the public include/linux/coresight.h so it can be shared
outside of drivers/hwtracing/coresight/, matching CORESIGHT_LAR and
CORESIGHT_DEVID already moved there.
