cache: include asm/cache.h for ARCH_DMA_MINALIGN definition

Browse source 
ARCH_DMA_MINALIGN will be used to allocate DMA buffers that are
aligned correctly.  In all current cases this means that the DMA
buffer will be aligned to at least the L1 data cache line size of
the configured architecture.  If the board configuration file
does not specify the architecture L1 data cache line size then the
maximum line size of the architecture is used to align DMA buffers.
