spi: rockchip: Signal unfinished DMA transfers
When using DMA, the transfer_one callback should return 1 because the
transfer hasn't finished yet.
A previous commit changed the function to return 0 when the DMA channels
were correctly prepared.
This manifested in Veyron boards with this message:
[ 1.983605] cros-ec-spi spi0.0: EC failed to respond in time
Fixes: ea9849113343 ("spi: rockchip: check return value of dmaengine_prep_slave_sg")
