x86/cpu: Introduce new microcode matching helper

Browse source

The 'x86_cpu_id' and 'x86_cpu_desc' structures are very similar and
need to be consolidated.  There is a microcode version matching
function for 'x86_cpu_desc' but not 'x86_cpu_id'.

Create one for 'x86_cpu_id'.

This essentially just leverages the x86_cpu_id->driver_data field
to replace the less generic x86_cpu_desc->x86_microcode_rev field.
