[U-Boot] [PATCH] ARC: cache: define CONFIG_SYS_CACHELINE_SIZE as ARCH_DMA_MINALIGN

[Alexey Brodkin]

Even though we don't use CONFIG_SYS_CACHELINE_SIZE in ARC-specific code
it is used a lot in different drivers for alignment purposes.

So we define it and make much more drivers at least compilable for ARC.
