Update the board_fit_config_name_match() to choose the right dtb based on the board name read from EEPROM.
Also restrict multpile EEPROM reads by verifying if EEPROM is already read

Do we actually need a different DTB to be used in SPL, in order to get the right DTB for full U-Boot? It's an intentional design decision here that we go board-specific as late as possible, so that it's clearer for custom designs what they do and do not need to modify.
