dmaengine: dw-axi-dmac: support DMAX_NUM_CHANNELS > 8
Added support for DMA controller with more than 8 channels.
DMAC register map changes based on number of channels.
Enabling DMAC channel:
DMAC_CHENREG has to be used when number of channels <= 8
DMAC_CHENREG2 has to be used when number of channels > 8
Configuring DMA channel:
CHx_CFG has to be used when number of channels <= 8
CHx_CFG2 has to be used when number of channels > 8
Suspending and resuming channel:
DMAC_CHENREG has to be used when number of channels <= 8 DMAC_CHSUSPREG
has to be used for suspending a channel > 8
