Add DMA driver and dt-binding document for Loongson1 SoCs.

Changelog
V4 -> V5:
Add the dt-binding document
Add DT support
Use DT information instead of platform data
Use chan_id of struct dma_chan instead of own id
Use of_dma_xlate_by_chan_id() instead of ls1x_dma_filter()
Update the author information to my official name
V3 -> V4:
Use dma_slave_map to find the proper channel.
Explicitly call devm_request_irq() and tasklet_kill().
Fix namespace issue.
Some minor fixes and cleanups.
V2 -> V3:
Rename ls1x_dma_filter_fn to ls1x_dma_filter.
V1 -> V2:
Change the config from 'DMA_LOONGSON1' to 'LOONGSON1_DMA',
and rearrange it in alphabetical order in Kconfig and Makefile.
Fix comment style.
