ARM: at91/dt: add specific DT soc init
This will allow to have static Device mapping and DT probe mapping for the
System Controller.
Temporary keep the call to ioremap_registers() until we have the binding
for the SDRAM/DDR Controller.
Temporary keep the main clock hardcoded to 12MHz until we have the binding
for the PMC.
