>From CCCFG register of eDMA3 we can get all the needed information for the
driver about the IP:
Number of channels: NUM_DMACH
Number of regions: NUM_REGN
Number of slots (PaRAM sets): NUM_PAENTRY
Number of TC/EQ: NUM_EVQUE
The ti,edma-regions; ti,edma-slots and dma-channels in DT are
redundant since the very same information can be obtained from the HW.
The mentioned properties can be removed from the binding document.
