The icside driver can be configured without DMA support, but it
doesn't compile in this case, because DMA operations are referenced.

I attach the configuration, that exposes this compilation error. This patch was
*NOT* tested on real hardware. I don't if the fix really does solve the
problem, but at least it is a hint that there is a problem.
