[PATCH v17 04/10] coresight: Move CORESIGHT_DEVID to linux/coresight.h

[Songwei Chai]

CORESIGHT_DEVID lives at a fixed, architecturally-defined offset
(0xfc8) within the generic CoreSight management register block, which
is also present on non-CoreSight-labelled components that follow the
same convention (e.g. the Qualcomm TGU). Keeping it private to
coresight-priv.h forces such drivers to redefine the same constant
under a different name instead of reusing it, as already done for
CORESIGHT_LAR/CS_LOCK/CS_UNLOCK.

Move CORESIGHT_DEVID into the public include/linux/coresight.h so it
can be shared outside of drivers/hwtracing/coresight/ as well.
