    AVR: target/122527 -- Don't use __load_N to load from __flash1.

    This patch fixes a case where a 3 byte or 4 byte load from __flash1
    uses __load_3/4 to read the value, which is wrong.

    This only occured when the device has ELPM but not ELPMx (avr31).

            the address-space is not ADDR_SPACE_FLASH.
