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.

The peripherals utilizing UART were required to register their own
ISR rountines. This means that all those peripherals drivers need
to know which IRQ line is attached to a UART controller, and all
the other config values required to register a ISR. This causes
scalibility issue as every board and peripherals have to define
those values.
Another reason for this patch is to support virtual serial ports.
Virtual serial ports do not have physical interrupt lines to
attach, and thus would not work.
This patch adds a simple callback mechanism, which calls a function
when UART interrupts are triggered. The low level plumbing still needs
to be done by the peripheral drivers, as these drivers may need to
access low level capability of UART to function correctly. This simply
moves the interrupt setup into the UART drivers themselves. By doing
this, the peripheral drivers do not need to know all the config values
to properly setup the interrupts and attaching the ISR. One drawback
is that this adds to the interrupt latency.
Note that this patch breaks backward compatibility in terms of
setting up interrupt for UART controller. How to use UART is still
the same.
This also addresses the following issues:
() UART driver for Atmel SAM3 currently does not support interrupts.
So remove the code from vector table. This will be updated when
there is interrupt support for the driver.
() Corrected some config options for Stellaris UART driver.
This was tested with samples/shell on Arduino 101, and on QEMU
(Cortex-M3 and x86).

This will build and flash the generated binary to the board.

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.
