x86/boot: Fix memremap() related build failure
The following commit:
5997efb96756 ("x86/boot: Use memremap() to map the MPF and MPC data")
causes new build failures on certain randconfigs:
drivers/sfi/sfi_core.c: In function ‘sfi_map_memory’:
drivers/sfi/sfi_core.c:104:10: error: implicit declaration of function ‘memremap’ [-Werror=implicit-function-declaration]
drivers/sfi/sfi_core.c:104:31: error: ‘MEMREMAP_WB’ undeclared (first use in this function)
This is a case of parasitic header dependencies: the sfi_core.c file indirectly
includes <linux/io.h> for typical - but not all configs.
Including <linux/io.h> explicitly solves the build failure.
