Adjust idec algorithm for Explorer B.0 format
The update to B.0 doesn't allow for a change to the register that
previously contained the MAJOR_REVISION value. Because of that
we are revising the logic that determines the EC level to be a
lookup based on a single number instead.
Ignore the MAJOR_RELEASE field from CHIP_INFO entirely, it will
always =1. Instead we will rely only on the EFUSE bits currently
designated for MINOR_RELEASE. Since we lost the ability to have
a common M.m we will just use a single incrementing value to
represent the ordinal revision number, regardless of major/minor,
i.e. the 1st revision is 0, the 2nd is 1, the 10th is 9, etc.
So that gives us these values for EFUSE_IMAGE_OUT_3[13:10]
A.0 = 0 = 0x10 in Host Firmware
A.1 = 1 = 0x11 in Host Firmware
B.0 = 2 = 0x20 in Host Firmware
B.1 = 3 = 0x21 in Host Firmware (if it were to happen)
