arcv2: Set IOC aperture so it covers available DDR
We used to use the same memory layout and size for a couple of
boards and thus we just hardcoding IOC aperture start and size.
Now when we're getting more boards with more memory on board we
need to have an ability to set IOC so it matches real DDR layout
and size.
Even though it is not really a must but for simplicity we assume
IOC covers all the DDR we have, that gives us a chance to not
bother where DMA buffers are allocated - any part of DDR is OK.
