Reading throught the new driver, I noticed that this cannot work on
big-endian CPUs, and the old DAC960 had exactly the same behavior.

To document this for the future, add a Kconfig dependency that prevents it
from being included in big-endian kernels.  Since the hardware is really
old and we never had a working driver on it for big-endian platforms,
it's unlikely to make a difference to users.
