rk27xx: sd: properly align buffer used for DMA transfers.
Commit 7d1a47cf ("Rewrite filesystem code (WIP)") exposed
bug in rk27xx sd driver. Buffer passed to sd_read/write_sectors()
doesn't has to be cacheline aligned. DMA transfers on
unaligned buffers is quiet dangerous thing.
Make sure that the buffer is aligned to cacheline size,
If not use a temporary aligned buffer for DMA transfer.
