Subject: [PATCH] Decode HT 1.02 in the same way as HT 1.03.

AMD K8 processors claim that they're using HyperTransport 1.02, but the
publicly available documentation (specifically the BKDG) states that the
HT version is 1.03 in reality.

lspci will issue a warning "!!! Possibly incomplete decoding" and only
decode some basic HT properties for HT versions before 1.03.
Move that boundary down to HT version 1.02.
