Public bug reported:

SRU Justification:

[Impact]
Currently, the VPD info stored in the EEPROM does not include a Rev ID. This 
field is incremented when a PN goes through minor HW changes. Sometimes, SW 
needs to differentiate the two versions of the card. Hence, this field should 
be supported in the EEPROM MFG partition.

[Fix]
EC (Engineering Changes) field is used to denote the HW Revision of a PN. Add 
it to the EEPROM MFG and provide a sysfs entry to access the same via 
mlx-bootctl.

[Test Case]
This field is typically programmed at the manufacturing step using the bfcfg 
tool which uses the write mechanism in the driver and then the MFG partition is 
locked. Reading the "rev" sysfs will show the current value.

[Regression Potential]
Can be considered minimum.
