dmaengine: dw-edma: Add changes to support Channel Separation
HDMA supports configurable DMA channel register space
separation which ranges from 256B to 32KB. Current implementation
supports 256B as default for DMA channel register space.
CPM6 supports the selection of channel register space via VSEC.
The default value for channel register space for CPM6 is 512B.
Updated the functions and methods to calculate the DMA channel
registers base address as per the selected channel separation
available as part of 'ch_space_sz'. Removed the unused function
__dw_regs() and structs, namely dw_hdma_v0_ch and dw_hdma_v0_regs.
