This allows at91_rtt_irq_fixup() to be used outside
of the mach-at91/ directory.
Adjust all call sites to include the at91_rtt header.
Deleting one .c file is another nice side effect of this move.

The at91 soc support inherited a complex scheme
from the kernel.
This schme did not really give any benefits, and when
starting to migrate at91sam9263ek to use DT it started
to get in the way for a proper way to do things.
Replace the former setup with a simple function
pointer that can be called from setup.c.

Add at91sam9263ek.dts to build.
Include mmc1 in at91sam9263ek.dts, as mmc1 is what the evaluation
kit uses for the SD card.
Add DT specific of_init
Adjust build to drop non-DT files from mach-at91
