It's better to discuss with x86 maintainers.

I don't see much advantage here. Without specific driver data it will be
degraded to something like:
if (bootcpu.model == INTEL_CPU_...)
...
with slight exception to heterogeneous SoCs.
In order to be compile tested we might introduce a header under
include/platform_data/x86 with these inliners like:
static inline bool is_x86_model_XX(void)
{
return bootcpu.model == XX; // it might be done in more generic way?
}
