[SRU][N:gke][PATCH 051/106] coresight: Remove unused stubs

[Tim Whisonant]

From: James Clark <james.clark at arm.com>

BugLink: https://bugs.launchpad.net/bugs/2117098

These are a bit annoying to keep up to date when the function signatures
change. But if CONFIG_CORESIGHT isn't enabled, then they're not used
anyway so just delete them.
