Account for Explorer's DMB_REVISION format in its SPD

We have been told that the field we are reading to figure out the
EC level of the OCMB via its SPD (offset 0x200) is going to say
0xA0 for the first version of the card, at IBM we would call this
EC 0x10. The Explorer manufacture has stated that they will increment
the 1st nibble when they do match card revisions, and the 2nd nibble
on minor revisions. This commit adds the logic to convert the
manufacture's revision format into IBM's EC level format. It also
updates the prebuilt cache we use in simics for axone to have the
expected 0xA0 value for the explorer SPD stored in the prebuilt cache
