- add more comments stating the relevant logic
- remove unused macro and variables
- change to use the disclaimer with SPDX identifier

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.
