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
register AXIDMA_CTRL_DMA_HS_SEL_n. Peripheral source number is
programmed in respective channel slots.
