1) Use ":" as a field seperator (that's probably obvious)

2) field 1 indicates the structure/contents of field 12.
   "pa" says field 12 is IODC data (16 bytes).
   "pci" says field 12 is PCI vendor/product (4 bytes).

3) IODC data format should be documented in IOACD or somewhere.
   PCI isn't. It's the PCI vendor/product ID from config space.

Short (but cryptic) answer is first three "nibbles" (4-bit quantities)
are HV model. Next nibble is HV rev.  SV rev is the high order nibble
of the 5th byte (iodc[4]). SV model the following 5 nibbles.

So printing the values in hex should make them easier to eye-ball
and correlate to either hardware.c entries or PCI output.

The "pa" vs. "pci" probably makes it look inconsistent.
