Subject: [PATCH] drm/amd/pm: set vangogh_set_apu_thermal_limit storage-class-specifier to static

gcc with W=1 reports
drivers/gpu/drm/amd/amdgpu/../pm/swsmu/smu11/vangogh_ppt.c:1600:5:
  error: no previous prototype for ‘vangogh_set_apu_thermal_limit’ [-Werror=missing-prototypes]
 1600 | int vangogh_set_apu_thermal_limit(struct smu_context *smu, uint32_t limit)
      |     ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~

vangogh_set_apu_thermal_limit is only used in vangogh_ppt.c, so it should be static
