mlxbf-bootctl: Support sysfs entries for MFG fields
This patch extends the mlxbf-bootctl driver's sysfs entries
to support read and write access for the manufacturing (MFG)
fields in the board-level EEPROM. The MFG fields are set
once during the board manufacturing phase, and then the MFG
fields are write-protected.
