dts: Set preferred numa options in bootargs

The default cmdline adjustment is now numa_policy=interleave for 2711 and 2712, and additionally system_heap.max_order=0 iommu_dma_numa_policy=interleave for just 2712 (due to its better iommu support). The key setting numa=fake=<n> is not set here, so we will boot with a single numa region and behaviour should be pretty much unchanged from before this PR.
