Changes since v3:
- enhance dt-binding documents based on Rob's comments
- make consistent among all comments
- perfer ordering declarations longest to shortest
- fix warning reported from kbuild test robot
- add patch 4 and 5 to keep Fengguang and Julia's effort

Changes since v2:
- remove extra tasklets and refactor driver for letting descriptors being processed ASAP.
- add more comments stating the relevant logic
- remove unused macro and variables
- change to use the disclaimer with SPDX identifier
- add mt7622 support
- refine hardware initialization sequence
- add tx_status support for DMA_RESIDUE_GRANULARITY_SEGMENT
- refine remove handler with killing vc's tasklet

Changes since v1:
- fix typo in the commit message.
- delete status shown in the dt-binding example.

This patchset introduces support for MediaTek High-Speed DMA controller
(MTK-HSDMA) Currently, the driver is already tested successfully with
dmatest module on MT7622 and MT7623 SoC. 

MTK-HSDMA on MT7622/23 SoC has a single ring which is dedicated for
doing memory-to-memory transfer through ring-based descriptor management.
Even though there is only a single ring available inside HSDMA, the
driver is being extended to the support for multiple virtual channels
processing simultaneously by means of DMA_VIRTUAL_CHANNELS.
