Any drivers which support ACPI and Device Tree probing need to include
both respective header files. Without this patch, if a driver is being
used on a platform which does not support ACPI and subsequently does not
have the config option enabled, but includes linux/acpi.h the build
breaks with:
In file included from ../include/acpi/platform/acenv.h:150:0,
