Looks like it was caused by:
commit 8b3444852a2b58129ee68a8dd69fef81ceb902a1

sata_dwc_460ex: move to generic DMA driver
The SATA implementation based on two actually different devices, i.e. SATA
and
DMA controllers.
For Synopsys DesignWare DMA we have already a generic implementation of the
driver. Thus, the patch converts the code to use DMAEngine framework and
dw_dmac driver.
In future it will be better to split the devices inside DTS as well like
it's
done on other platforms.
