dmaengine: pl08x: Add support for the DMA slave map

This patch adds support for the new channel request API introduced
in commit a8135d0d79e9d0ad3a4ff494fceeaae83
"dmaengine: core: Introduce new, universal API to request a channel".

param field of struct dma_slave_map type entries in the platform
data structure should be pointing to struct pl08x_channel_data
of related DMA channel.
