DRM: bug: RADEON_DEBUGFS_MAX_{NUM_FILES => COMPONENTS}

The value of RADEON_DEBUGFS_MAX_NUM_FILES has been used to
specify the size of an array, each element of which looks
like this:

  struct radeon_debugfs {
          struct drm_info_list    *files;
          unsigned                num_files;
  };

Consequently, the number of debugfs files may be much greater
than RADEON_DEBUGFS_MAX_NUM_FILES, something that the current
code ignores:

  if ((_radeon_debugfs_count + nfiles) > RADEON_DEBUGFS_MAX_NUM_FILES) {
          DRM_ERROR("Reached maximum number of debugfs files.\n");
          DRM_ERROR("Report so we increase RADEON_DEBUGFS_MAX_NUM_FILES.\n");
          return -EINVAL;
  }

This commit fixes this make, and accordingly renames:

  RADEON_DEBUGFS_MAX_NUM_FILES

to:

  RADEON_DEBUGFS_MAX_COMPONENTS
