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'.

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 is the last step before obsoleting DEVICE_DEFINE() and
DEVICE_INIT_CONFIG_DEFINE().

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
object.

Ben Walsh identified a few functions can be removed as they provide
duplicate code except for one small variant (register number). Making
a common function that takes the register position as an input, it is
possible to remove an entire function, saving on code space.

The production version is slightly different than the internal
development board, so the pin mux description has been updated.

Static function was declared after it was used.

We had one pinmux per platform with support for multiple boards.
This moves pinmuxing to boards as first step. Common functions that
are exposed by the API need to be moved to driver while keeping the
muxing configuration with the boards.
