Enabling individual I2C controller is done in the SoC kconfig defaults.
There is no need to do that in the board defaults.

The pinmux base address and number of pins are now defined in SoC or board
header files instead of specifying them in kconfig. This is because
the pinmux ties directly to the SoC (or board expanders) so the base
address and number of pins do not need to be configurable in kconfig.

There are two major issues with the kconfig:
() Some of the config options have incorrect dependencies inside help
under menuconfig. For example, CONFIG_GPIO depends on BOARD_GALILEO.
() Since the SoC and board specific kconfig files are parsed first,
the help screen would say, for example, CONFIG_SPI is defined at
arch/arm/soc/fsl_frdm_k64f/Kconfig. This is incorrect because
the actual config is defined in drivers/spi/Kconfig.
These cause great confusion to users of menuconfig/xconfig.
To fix these, the SoC and board defaults are now to be parsed last.
Note that the position swapping of defaults in this patch is due to
the fact the the default parsed last will be used.
And, spi_test is broken due to the fact that it requires
CONFIG_SPI_INTEL_PORT_1, but never enables it anywhere. This is
bypassed for now.

Before moving pinmux related code to 'drivers/pinmux' fix their return
codes to be consistent with the rest of the API.

All driver APIs (i2c, spi, gpio, etc.) return 'int' type, but pinmux
APIs. So this patch changes the returning type from 'uint32_t' to
'int' from include/pinmux.h and fixes all pinmux drivers according.
Besides keeping consistency between all drivers APIs, this patch is
also applicable for the errno.h code transition. Pinmux drivers will
return negative errno.h codes so returning 'int' is more suitable
than 'uint32_t'.

This makes the board selection dependent on SoC selection. For example,
select Atmel SAM3 will only allow "Arduino Due" as board selection.
This disallows incompatible SoC/board combination, like K64F with
Arduino Due.

The pinmux API was modified to expand the meaning of the 'func' argument
to allow it to represent more than a pre-configured function. This was done
to reasonably accommodate a larger range of pin configuration options
offered by other MCUs, such as the Freescale K64 (up to 8 pin functions,
plus interrupt, pullup/down, drive strength, open-drain, slew rate, etc.).
This allows bit fields to be used to define various settings.

This adds the pinmux driver for use with Arduino Due.
The default for pinmux (mostly) reflects the pin layout
on the board.

This adds very basic support for running on Arduino Due.
Only the nanokernel hello_world has been tested.
