cmd: tlv_eeprom: enable 'dev' subcommand before 'read'

Move the handler for "tlv_eeprom dev X" command to the beginning of
do_tlv_eeprom, to allow using it before issuing a "read" command for
currently selected eeprom.

Also remove the check if eeprom exists, since that can only work after
the first execution of read_eeprom triggered device lookup.
Instead accept values up to the defined array size (MAX_TLV_DEVICES).
