Include linux/io.h for readl()/writel().

When built on x86_64 w/ COMPILE_TEST=y:
../drivers/gpu/drm/hisilicon/kirin/dw_dsi_reg.h:93:16: error: implicit declaration of function ‘readl’ [-Werror=implicit-function-declaration]
   93 |         orig = readl(addr);
      |                ^~~~~
../drivers/gpu/drm/hisilicon/kirin/dw_dsi_reg.h:96:9: error: implicit declaration of function ‘writel’ [-Werror=implicit-function-declaration]
   96 |         writel(tmp, addr);
      |         ^~~~~~
