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.

In the pinmux_dev driver for the Quark SE development board in
pinmux_dev_set() the variable 'mode' was used, but it should have been
'func'. This was causing a compilation error:
/home/vinicius/work/zephyr/boards/quark_se_devboard/pinmux.c:
In function 'pinmux_dev_set':
/home/vinicius/work/zephyr/boards/quark_se_devboard/pinmux.c:245:23:
error: 'mode' undeclared (first use in this function)
uint32_t mode_mask = mode << (pin_no << 1);

CC2520 can handle up to 8Mhz SPI SCLK frequency, thus let's use it. It
will help to avoid timing issuse while transmitting and receiving (i.e.:
getting registers or buffers from CC2520 through SPI will be fast and
won't impede RX/TX events too much).

The radio driver was using DW spi and gpio drivers hardcoded.
Now it will check if SPI_DW or SPI_QMSI is set.

Using level will just flood the handler, as the concerned gpio pins
stays on level for some time.

Using the latest SDK (0.7.2) you can flash directly using make
by specifying the board, for example
make BOARD=arduino_101 flash
This will build and flash the generated binary to the board.

Rename it to DEVICE_DEFINE() so that it fits in the 'device' namespace.

Rename it to DEVICE_INIT_CONFIG_DEFINE(), because (a) it was not fitting
in any namespace and (b) it is not used to declare, but rather define a

SPI needs to get its interrupt configured as triggering on level high to
work properly. This is specific to Quark SE (thus x86 core).

SPI, to control the CC2520 chip, is the only generic feature and thus
the only one configurable through Kconfig. GPIO on the other end depends
a lot on the SoC/Board. Adding a slave select option as well.
