UPSTREAM: dm: core: Round up size when allocating so that it is cache line aligned 

The size variable may not be always be a mulitple of
ARCH_DMA_MINALIGN and using it to flush cache leads to cache
misaligned warnings.

Therefore, round up the size to a multiple of ARCH_DMA_MINLAIGN
when allocating private data.
