Sorry for not mentioning the version immediately
It seems my system does not find the version you have (I use pkgs not ports)

pkg search devcpu-data
  devcpu-data-20211109           AMD and Intel CPUs microcode updates
  devcpu-data-amd-20211115       AMD CPUs microcode updates
  devcpu-data-intel-20210608     Intel CPU microcode updates

pkg info devcpu-data-intel-20210608

Wanted to test with another 06-86-05 file (see if detected as compatible), but
https://github.com/intel/Intel-Linux-Processor-Microcode-Data-Files/tree/main/intel-ucode
does not list a 06-86-05 file indeed.

https://github.com/intel/Intel-Linux-Processor-Microcode-Data-Files/releases
states it was removed in the latest release:
Removed Platforms
Processor       Stepping        F-M-S/PI        Old Ver         New Ver        
Products
SNR     B0      06-86-04/01     0b00000f                Atom P59xxB
SNR     B1      06-86-05/01     0b00000f                Atom P59xxB

Still interesting that the CPU revision seems correctly encoded in the file:
od -t x4 /usr/local/share/cpucontrol/06-86-05.01 | head -1
0000000          00000001        0b00000f        02172021        00080665

but cpucontrol detects it as a file compatible with 06-8e-0c.
