Linux only considers the value of CONFIG_ARCH_DMA_DEFAULT_COHERENT if
the architecture also defines either of:
- CONFIG_ARCH_HAS_SYNC_DMA_FOR_DEVICE
- CONFIG_ARCH_HAS_SYNC_DMA_FOR_CPU
- CONFIG_ARCH_HAS_SYNC_DMA_FOR_CPU_ALL
We don't have those in barebox and also have less architectures to
support, so we'll just select ARCH_DMA_DEFAULT_COHERENT from all
architectures where this applies to: x86, sandbox and RISC-V.
RISC-V already selects it, so we add it to the other two.
