You can probably do something like

#ifdef CONFIG_ARM
#include <asm/cputype.h>
#else
static inline read_cpuid_id(void) { return 0; }
#endif

Then again, ideally drivers don't even have to know about this,
but would distinguish between devices based on the
compatible string for the particular device.
