DMAENGINE: ste_dma40: rewrote LCLA entries allocation code
...
LLI allocation is now done on job level instead of channel level.
Previously the maximum length of a linked job in hw on a logical
channel was 8, since the LLIs where evenly divided. Now only
executing jobs have allocated LLIs which increase the length to
a maximum of 64 links in HW.

DMAENGINE: ste_dma40: interrupts only on dst
...
We don't want interrupts when the source is done, only when
the destination is done and everything is complete at the
recieveing end of a transfer.
