x86/cpu: Move AMD erratum 1386 table over to 'x86_cpu_id'

Browse Source 
The AMD erratum 1386 detection code uses and old style 'x86_cpu_desc'
table. Replace it with 'x86_cpu_id' so the old style can be removed.

I did not create a new helper macro here. The new table is certainly
more noisy than the old and it can be improved on. But I was hesitant
to create a new macro just for a single site that is only two ugly
lines in the end.
