!466 LoongArch: fix compile error when using make allmodconfig

Merge Pull Request from: @Hongchen_Zhang 
 
1. when compile for arm platform using make allmodconfig,compile error occurred at drivers/gpu/drm/loongson/lsdc_i2c.o.
So we add the required io.h to make it fine.
2. fix drivers/vfio/pci/vfio_pci_rdwr.c compile error on LoongArch by change the 
  definition of iounmap.
