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.
