Merge PR #19575 (changes to pr-extendend_hw_ver_rev_format)

- 4096 of 3 hex digits each for rev and ver is enough.
    #defines used in SPI versions do not be long format, use use the macro
 - Board provides a prefix and the formatting is sized and built in
 - No need for funky board_get_base_eeprom_mtd_manifest interface
    Original mft is used where the abstraction is done with the MFT interface
