dma-contiguous: fix the Kconfig entry for CONFIG_DMA_NUMA_CMA

Browse source

enabled, and random config options shouldn't be default unless there
is a good reason.  Replace the default NUMA with a depends on to fix both
issues.

Enable this option to get numa CMA areas so that NUMA devices
can get local memory by DMA coherent APIs.
