This address does not look correct. This appears to be the address of
the AGIC. I think it should be 2900000, however, I also wonder if we
should even bother with an address for the aconnect as this is just a
bus and we don't specific a 'reg' property.

This should be 0x1fffff.

I think that this should also be "agic: interrupt-controller@xxxx" to
conform with standard names. Sorry the Tegra210 version is not the best
reference!
