Where missing add compatible = "soc-nv-flash". Also added a label for
all the soc-nv-flash that we might use in the future.

Added I2C bus (TWI) driver for Atmel SAM MCU family. Only
I2C Master Mode with 7 bit addressing is currently supported.
Tested on Arduino Due board.

This patch add the unit-address component to memory and flash
nodes. According to the DT specification, the unit-address of
a node must match the first address specified in the reg
property of the node.

Remove compatible = "flash" from any node that has it as this doesn't
have any well defined meaning right now. Also update any compatible =
"sram" to be "mmio-sram" (as there's a binding in linux for this).

The SAM4S, SAM3X, SAME70 all use the uart_sam.c serial
driver. This patch puts the configuration in DTS and
out of Kconfig. The SAME70 uses the USART as well.
USART DTS support for the SAME70 is also in this patch.

The Sam3x HAL defines __NVIC_PRIO_BITS to 4.
Fixes an issue where interrupt priorities and masking
were not being done correctly.

Now that we can utilize label in the device tree we can convert to
getting the device name for the Atmel SAM3 UART out of the device
tree instead of from Kconfig.
