[PATCH] dt-bindings: arm: Fix CoreSight CTI Kconfig symbol

[Karl Mehltretter]

The option exposing CoreSight CTI integration registers is
CONFIG_CORESIGHT_CTI_INTEGRATION_REGS, not
CONFIG_CORESIGHT_CTI_INTEGRATION_TEST.

DT bindings should not be referring to kernel kconfig symbols (or 
anything else in the kernel) in the first place.

Agreed - the comment in general is correct but the last sentence in the 
paragraph should drop the config reference. e.g.

"This information might be found by using the CTI Integration Test 
registers to explore the trigger connections between CTI and other 
CoreSight components."

The coresight/KConfig file itself adequately documents adding this 
support and the perils therein.
