Subject: [PATCH] coresight: tmc: mark coresight_tmc_groups with static

From: Chunyan Zhang <chunyan.zhang@...soc.com>

Sparse reports a warning like:
drivers/hwtracing/coresight/coresight-tmc.c:364:30: warning: symbol
'coresight_tmc_groups' was not declared. Should it be static? [sparse]

coresight_tmc_groups is used in the local file only, so it should be
marked with static.
