bcm63xx_enet: split DMA channel register accesses
The current bcm63xx_enet driver always uses bcmenet_shared_base whenever
it needs to access DMA channel configuration space or access the DMA
channel state RAM. Split these register in 3 parts to be more accurate:
- global DMA configuration
- per DMA channel configuration space
- per DMA channel state RAM space
This is preliminary to support new chips where the global DMA
configuration remains the same, but there is a varying number of DMA
channels located at a different memory offset.
