dsp5680xx: fix clang error core.UndefinedBinaryOperatorResult

Browse Source 
Clang get confused by initializing the array uint16_t lock_word[],
casting it to (uint8_t *), then accessing the second element of
the uint8_t pointer.

  src/target/dsp5680xx.c:2046:41: warning: The left operand of '<<'
    is a garbage value [core.UndefinedBinaryOperatorResult]
        uint16_t tmp = (buffer[0] | (buffer[1] << 8));
                                     ~~~~~~~~~ ^
Fix it by replacing the array with a single uint16_t.

The code is still depending on host endianness; no fix for this is
proposed.
