cmd: eeprom: Add StarFive VisionFive 2 board support

Rename CONFIG_SYS_DEF_EEPROM_ADDR to CONFIG_SYS_I2C_EEPROM_ADDR
based on current usage.

Convert CONFIG_SYS_I2C_EEPROM_BUS, CONFIG_SYS_I2C_EEPROM_ADDR_LEN,
CONFIG_SYS_EEPROM_SIZE, CONFIG_SYS_EEPROM_PAGE_WRITE_BITS and
CONFIG_SYS_EEPROM_PAGE_WRITE_DELAY_MS to Kconfig.
