Bunch of core and driver fixes:
- Couple of fixes in core around dma_chan_put() for kref underflow, user
after free bug and waiting for rcu readers for dma devices
- mmp sg length and wrong extended DRCMR base for SpacemiT K3
- hardware buffer descriptor chain fix for xilinx dma
- sun6i fixes for status behaviour and dma position registers
- runtime pm reference leak fix for sprd driver
