x86/cpu: Replace PEBS use of 'x86_cpu_desc' use with 'x86_cpu_id'

x86/cpu: Replace PEBS use of 'x86_cpu_desc' use with 'x86_cpu_id'

The 'x86_cpu_desc' and 'x86_cpu_id' structures are very similar.
Reduce duplicate infrastructure by moving the few users of
'x86_cpu_desc' to the much more common variant.

The existing X86_MATCH_VFM_STEPS() helper matches ranges of
steppings. Instead of introducing a single-stepping match function
which could get confusing when paired with the range, just use
the stepping min/max match helper and use min==max.

Note that this makes the table more vertically compact because
multiple entries like this:

       INTEL_CPU_DESC(INTEL_SKYLAKE_X,          4, 0x00000000),
       INTEL_CPU_DESC(INTEL_SKYLAKE_X,          5, 0x00000000),
       INTEL_CPU_DESC(INTEL_SKYLAKE_X,          6, 0x00000000),
       INTEL_CPU_DESC(INTEL_SKYLAKE_X,          7, 0x00000000),

can be consolidated down to a single stepping range.
