Subject: [PATCH] drm/sti: Add __iomem for mixer_dbg_mxn's parameter

Sparse complains about incorrect type in argument 1.
expected void const volatile  __iomem *ptr but got void *.
so modify mixer_dbg_mxn's addr parameter.

Reported-by: kernel test robot <lkp@...el.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202411191809.6V3c826r-lkp@intel.com/
Fixes: a5f81078a56c ("drm/sti: add debugfs entries for MIXER crtc")
