remoteproc: da8xx: don't select CMA on no-MMU
We can only use CMA on systems that have an MMU, because of the requirement to use memory migration. NOMMU systems are rather constrained to start with, but it seems reasonable to assume that DMA allocations can still succeed in the constrained case for remoteproc on NOMMU, so this patch changes the da8xx implementation to not rely on CMA when the MMU is disabled.
