redhat/configs: remove CONFIG_DMA_PERNUMA_CMA and switch CONFIG_DMA_NUMA_CMA off

CONFIG_DMA_PERNUMA_CMA was replaced by CONFIG_DMA_NUMA_CMA, so remove
the old, and continue to leave off with CONFIG_DMA_NUMA_CMA.

What memory does enabling these CONFIG's to yes consume?
or does it 'just' turn on the ability to use CMA areas, and (per-numa) cma-
size has to be set to consume memory?

I am going to look at that this week, and try to get some good data on it, but
wanted to keep it in sync with the previous behavior from
CONFIG_DMA_PERNUMA_CMA for now while that is figured out.

@jsnitsel @ddutile - we are rebasing today.   Is this worth approving and
merging today or just wait and rebase tomorrow?

I guess this already resolved itself? :smile:
