This will allow to have static Device mapping and DT probe mapping for the

Temporary keep the call to ioremap_registers() until we have the binding

http://www.calao-systems.com/articles.php?lng=en&pg=6099

this daughter board add the following device:
 - Micro-SD socket
 - TTL 3V3 - (Tx/Rx/RTS/CTS)
 - I2C port
 - 0.96" Serial OLED Display Module (over UART)
 - MP3 decoder with Micro & Speakers
 - 4x PB, 4x Leds (Blue), 3x Leds (Green, Orange, Red)

for now we add only the 2 UARTs, 4 Buttons, 7 leds and i2c via DT

used_led1 will not be re-add via DT as it's used by the motherboard too

The SoC nature is deduced from the device tree "compatible" string.
For non-device-tree configurations, backward compatibility is maintained
by using the default 16 bit counter configuration.

Nicolas Ferre 8014d6f4dd ARM: at91: AIC and GPIO IRQ device tree initialization
Both AIC and GPIO controllers are now using the standard of_irq_init()
function to initialize IRQs in case of DT use.
The DT specific initialization functions are now separated from the
non-DT case and are now using "linear" irq domains.
The .map() irqdomain operation is responsible for positioning the IRQ
handlers. In AIC case, the Linux IRQ number is directly programmed in
the hardware to avoid an additional reverse mapping operation.
The AIC position its irq domain as the "default" irq domain.

For DT case, the priority is not yet filled in the SMR. It will be the
subject of another patch.

Jean-Christophe PLAGNIOL-VILLARD e8729dda3f ARM: at91/board-dt: drop default console
This default console mechanism is not used if the console is selected
by command line (console= parameter).
Dropping this will simplify the compilation of multiple SoC in the same
kernel image.

Jean-Christophe PLAGNIOL-VILLARD 69f6a27bf4 Atmel: move console default platform_device to serial driver
This variable spread on every SoC that is using the atmel_serial.c
driver can be included directly into the latter.

This will allow to compile multiple soc in the same kernel.
