Architectures others than x86 have a stub implementation calling
WARN_ON_ONCE(). The appropriate headers need to be included, otherwise
the header-test target will fail with:
HDRTEST drivers/gpu/drm/i915/i915_mm.h
In file included from <command-line>:
./drivers/gpu/drm/i915/i915_mm.h: In function ‘remap_io_mapping’:
./drivers/gpu/drm/i915/i915_mm.h:26:2: error: implicit declaration of function ‘WARN_ON_ONCE’ [-Werror=implicit-function-declaration]
26 | WARN_ON_ONCE(1);
| ^~~~~~~~~~~~
v2: Do not include <linux/printk.h> since call to pr_err() has been
removed
Fixes: 67c430bbaa ("drm/i915: Skip remap_io_mapping() for non-x86 platforms")
