iio: accel: mma9551_core: use size in words for word buffers
Change the prototype for the mma9551_read/write_*_words functions
to receive the length of the buffer in words (instead of bytes) since
we are using a word buffer. This will prevent users from sending an
odd number of bytes for a word array.
