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 Sam4x HAL defines __NVIC_PRIO_BITS to 4. Fixes an issue where
interrupt priorities and masking were not being done correctly.
