arch/x86/cpu: introduce and use device_match_mask
Instead of always doing exact matches between the CPUID read in identify_cpu and the device entries of the CPU device ID table, offer the possibility to use a bit mask in the CPUID matching. This allows covering all steppings of a CPU family/model with one entry and avoids that case of a missing new stepping causing the CPUs not being properly initialized. Some of the CPU device ID tables can now be deduplicated using the CPUID_ALL_STEPPINGS_MASK define, but that's outside of the scope of this patch.
