  There are some __iomem type casting being missed in previous patch.
Fix them here.

Fixes: 5bd3990723bd ("MIPS: Loongson64: Prefix ipi register address pointers with __iomem")
Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202307020639.QCZOKp8B-lkp@intel.com/
Signed-off-by: Jiaxun Yang <jiaxun.yang@flygoat.com>
