dmaengine: dw-axi-dmac: Remove free slot check algorithm in dw_axi_dma_set_hw_channel

Removed free slot check algorithm in dw_axi_dma_set_hw_channel. For 8
DMA channels, use respective handshake slot in DMA_HS_SEL APB register.

For every channel, an dedicated slot is provided in  hardware handshake
