coresight: stm: Remove set but not used variable 'res_size' 



Fixes gcc '-Wunused-but-set-variable' warning:

drivers/hwtracing/coresight/coresight-stm.c: In function 'stm_probe':
drivers/hwtracing/coresight/coresight-stm.c:796:9: warning:
 variable 'res_size' set but not used [-Wunused-but-set-variable]

It never used since introduction in commit 237483aa ("coresight: stm:
adding driver for CoreSight STM component")
