This commit adds Device-Tree instances of the Flash controller
to the SAM3X, SAM4E and SAM4S series. The Flash-Controller
is used to get the unique device identifier.

Introduce a standard watchdog alias 'watchdog0' that can be utilized
by sample/test code in the future. This helps remove the need for
CONFIG_WDT_0_NAME in dts_fixup.h files.

The true mmio-sram nodes should not have had a 'device_type' property.
Remove it from the cases that we clearly know are SRAM.

This commit adds 'clock-frequency' property to the cpu nodes.
The clock frequency specified in the added property is used
during platform configuration. Examples:
- The SWO logger uses clock frequency to configure SWO output.
- Plenty of platforms need CPU clock specified for their HAL.
- Most of devices with USB needs information about CPU clock
in order to configure USB clock source.

Newer DTC now warns about mismatch between the reg and unit-address.
Most of these cases are due to case not matching, so fix thoses so
everything is lowercase.

Adding watchdog driver for sam SoC. The current implemntation just
diables the watchdog on device boot.
This PR adds the following support for SAM3X, SAM4S and SAME70
1. Activate processor reset
2. Activate all reset
3. Generate interrupt on watchdog timer expiration.

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.

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.
