Changes since v3:
- simplify the ISR and management on descriptors by removing tasklet and ASYNC_TX_ENABLE_CHANNEL_SWITCH
- remove useless field in mtk_cqdma_vdesc structure
- change dev_info to dev_dbg
- fix typos
Changes since v2:
- fix build warning for kernel with DMA address in 32-bit
Changes since v1:
- remove unused macros, typos
- leverage ASYNC_TX_ENABLE_CHANNEL_SWITCH to maintain DMA descriptor list
