The files for the Arduino Due needed to be updated to use the new
configuration when the SoC moved from the atmel_sam3 directory to
the atmel_sam/sam3x directory.

Found out that the SAM3 series is not a single series. There are actully
3 different series, 3U, 3A, and 3X.

Convert code to use u{8,16,32,64}_t and s{8,16,32,64}_t instead of C99
integer types. There are few places we dont convert over to the new
types because of compatiability with ext/HALs or for ease of transition
at this point. Fixup a few of the PRI formatters so we build with newlib.

This is a start to move away from the C99 {u}int{8,16,32,64}_t types to
Zephyr defined u{8,16,32,64}_t and s{8,16,32,64}_t. This allows Zephyr
to define the sized types in a consistent manor across all the
architectures we support and not conflict with what various compilers
and libc might do with regards to the C99 types.
We introduce <zephyr/types.h> as part of this and have it include
<stdint.h> for now until we transition all the code away from the C99
types.
We go with u{8,16,32,64}_t and s{8,16,32,64}_t as there are some
existing variables defined u8 & u16 as well as to be consistent with
Zephyr naming conventions.

Added serial (UART) driver for Atmel SAM MCU family.
Note:
- Error handling is not implemented
- The driver works only in polling mode, interrupt mode is
not implemented.

same70/soc.h provided IRQ ids as #define. This is no longer
necessary as gen_isr_tables mechanism, which was recently
introduced, supports IRQ ids as enums. These are provided
directly by Atmel ASF library.

In Atmel SAM Family of MCUs, the watchdog is enabled by default at boot.
The watchdog once disabled, cannot be re-enabled back without a reset.
Hence disabling the Watchdog needs to be handled via the Watchdog driver.

This is a zero-copy networking implementation of Ethernet driver.
Limitations:
- one shot PHY setup, no support for PHY disconnect/reconnect
- no support for devices with DCache enabled due to missing
non-cacheable RAM regions in Zephyr.
