mb/prodrive/atlas: Rework EEPROM layout structures
To avoid having to calculate the length of a struct separately, rework
the code to give the struct a tag name, so that `sizeof()` can be used
instead. This involves refactoring the `get_emi_eeprom_vpd()` function
to return a struct instead of a union, so callers can no longer access
the EEPROM data as an array of bytes without additional code, but this
array view is only used inside `get_emi_eeprom_vpd()` when reading the
data from EMI.
