misc: habanalabs: goya: goya_coresight: Remove set but unused variable 'val'
No attempt to check the return value of RREG32() has been made
since the call was introduced a year ago.
Fixes W=1 kernel build warning:
drivers/misc/habanalabs/goya/goya_coresight.c: In function ‘goya_debug_coresight’:
drivers/misc/habanalabs/goya/goya_coresight.c:643:6: warning: variable ‘val’ set but not used [-Wunused-but-set-variable]
643 | u32 val;
