[PATCH] coresight: add module license

[Arnd Bergmann]

From: Arnd Bergmann <arnd at arndb.de>

When built as a loadable module, coresight now causes a warning about
missing license information.

WARNING: modpost: missing MODULE_LICENSE() in drivers/hwtracing/coresight/coresight.o

Fixes: 8e264c52e1da ("coresight: core: Allow the coresight core driver to be built as a module")
