Following what was done in drm_cache.c, when the stub for remap_io_mapping() was added in commit 67c430bbaae1 ("drm/i915: Skip remap_io_mapping() for non-x86 platforms"), it included a log message with pr_err(). However just the warning is already enough and switching to WARN_ONCE() allows us to keep the log message while avoiding log spam.
