Handle more Vortex CPU's from Andrius V.
While here refactor the code to make it smaller.

 -

 It seems that AMD zen2's CPUID 0x80000006 leaf's spec has changed.
The EDX register's acsociativity field has 9. In the latest available document,
it's a reserved value. I have no access to zen2's document, but many websites
say that the acsociativity is 16. Add it.

 -

- AMD CPUID Fn8000_0001d Cache Topology Information leaf is almost the same as
  Intel Deterministic Cache Parameter Leaf(0x04), so make new
  cpu_dcp_cacheinfo() and share it.
- AMD's L2 and L3's cache descriptor's definition is the same, so use one
  common definition.
- KNF.

XXX Split some common functions to new identcpu_subr.c or use #ifdef _KERNEK
... #endif in identcpu.c to share from both kernel and cpuctl?
