dmaengine: pl08x: allocate OF slave channel data at probe time
The current OF translation of channels can never work with any DMA client using the DMA channels directly: the only way to get the channels initialized properly is in the dma_async_device_register() call, where chan->dev etc is allocated and initialized. Allocate and initialize all possible DMA channels and only augment a target channel with the periph_buses at of_xlate(). Remove some const settings to make things work.
