mei: bus: enable OS version only for SPT and newer

Sending OS version for support of TPM2_ChangeEPS() is required only
for SPT FW (HMB version 2.0) and newer.
On older platforms the command should be just ignored by the firmware
but some older platforms misbehave so it's safer to send the command
only if required.

Fixes: 7279b238bade (mei: send OS type to the FW)
