Fixes the following W=1 kernel build warning(s):

 drivers/soc/tegra/fuse/speedo-tegra124.c: In function ‘tegra124_init_speedo_data’:
 drivers/soc/tegra/fuse/speedo-tegra124.c:105:38: warning: variable ‘soc_iddq_value’ set but not used [-Wunused-but-set-variable]
 drivers/soc/tegra/fuse/speedo-tegra124.c:105:22: warning: variable ‘gpu_iddq_value’ set but not used [-Wunused-but-set-variable]
 drivers/soc/tegra/fuse/speedo-tegra124.c:105:6: warning: variable ‘cpu_iddq_value’ set but not used [-Wunused-but-set-variable]
