sh: Kill off MAX_DMA_ADDRESS leftovers.

Browse Source 
We don't support the ISA DMA API, so this is only ever misused. The
dma-sh case inadvertently broke the dreamcast case by testing the wrong
variable for the total number of channels, so this fixes that up too.

This allows you to forcibly update the maximum number of supported
DMA channels for a given board. If this is unset, this will default
to the number of channels that the on-chip DMAC has.

This allows you to specify the maximum number of DMA channels to
support. Setting this to a higher value allows for cascading DMACs
with additional channels.
