Kconfig: ti: Make board detect EEPROM addresses depend BOARD_DETECT

There is an option to enable the board detection for TI platforms.
If this is option is not set, there is no reason to set the EEPROM
bus address or chip address.

This patch makes both EEPROM_BUS_ADDRESS and EEPROM_CHIP_ADDRESS
depend on TI_I2C_BOARD_DETECT.
