debian: Add 32-bit MIPS architectures to COHERENT_DMA_ARCHS

Commit b7c4283 ("util: Add barriers
support for MIPS") added support for coherent DMA support for MIPS.
All MIPS architectures needs to be added to `COHERENT_DMA_ARCHS` (not
just the 64-bit variants).

The list of architectures that support coherent DMA gets very long,
because most architectures support it. So inverse the list to make it
easier to read.
