Subject: [PATCH] arm64: acpi: Export symbol for acpi_os_ioremap

The driver who calls the acpi_os_ioremap() cannot be compiled if the 'M'
is selected for the driver. The compiling log is as follows:
-->
MODPOST Module.symvers
ERROR: modpost: "acpi_os_ioremap" [drivers/soc/hisilicon/xxx.ko] undefined!
scripts/Makefile.modpost:136: recipe for target 'Module.symvers' failed
make[1]: *** [Module.symvers] Error 1

So this patch exports symbol for acpi_os_ioremap.
