[PATCH V2 0/3] dmaengine: xilinx_dma: Fixes and optimizations for AXIDMA and MCDMA channel management

[Suraj Gupta <suraj.gupta2@amd.com>]

This patch series addresses issues and optimizations in the Xilinx
AXI DMA and MCDMA drivers:
1. Fix channel idle state management in the interrupt handlers.
2. Enable transfer chaining by removing unnecessary idle restrictions.
3. Optimize control register writes and channel start logic.

Note: The patches in this series were part of following IRQ coalescing
series which is under discussion:

Changes in V2:
- Apply similar fixes and optimizations to MCDMA as well.
- Expand the 1/3 commit description with when the described issue occurs.
