Subject: CONFIG_DMA_NOOP_OPS breaks ARM arch

After commit 7844572c633964c864d9f32dc3f2a8ffe5d70371, dma_noop_ops
are built only for architectures that use it.

For ARM architecture, CONFIG_DMA_NOOP_OPS is not selected, and cannot
be selected.

However, arch/arm/include/asm/dma-mapping.h is referencing dma_noop_ops:

static inline const struct dma_map_ops *get_arch_dma_ops(struct bus_type *bus)
{
return IS_ENABLED(CONFIG_MMU) ? &arm_dma_ops : &dma_noop_ops;
}

I will let a maintainer suggest the best resolution for this :)
