dmaengine: dw-axi-dmac: fix __le32 on set of CH_CTL_H_LLI_VALID

Browse Source 
When writing the lli->ctl_hi, this is an __le32 type so the
value being orred should be convered to __le32 by cpu_to_le32.

Fixes 1deb96c0fa ("dmaegine: dw-axi-dmac: Support device_prep_dma_cyclic()")
--
Note, the call to axi_chan_irq_clear() is passing lli->status_lo
through which is also an __le32 but it does not seem to be set
anywhere. Is this also a bug?
