If reading the serial/part number fails, returning an empty string is
very confusing. Instead, return "INVALID" to make problems obvious.

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.

Atlas stores VPD (Vital Product Data) in an I2C EEPROM, which is only
connected to the EC. In order for the host (x86) to be able to access
the VPD, the EC reads the EEPROM contents into a buffer in EC RAM and
provides the host with read-only access to this EC RAM buffer through
EMI (Embedded Memory Interface) 0.
The VPD layout is designed to be extensible yet backwards compatible.
The code in coreboot uses the revision field to know which fields are
valid, and will populate the rest with fallback values.
Use the serial number and part number in VPD to populate SMBIOS tables.
