arm64: asm-offsets: remove DMA_{TO,FROM}_DEVICE

The DMA_TO_DEVICE and DMA_FROM_DEVICE defintitons in asm-offsets
duplicate the common defintions from <linux/dma-direction.h> (which used
to live in <linux/dma-mapping.h>), and haven't been used from asseembly
code since commit:

  7eacf18 ("arm64: mm: Remove assembly DMA cache maintenance wrappers")

Remove them both.
