eafcba5e7a galileo: Add support for Clock module
This patch adds support for Contiki's clock module. All functions from
core/sys/clock.h are implemented, except clock_set_seconds() and clock_
delay_usec(). The CLOCK_CONF_SECOND macro is set to 128. This value
seems to be good enough since several platforms used it. Finally, we
use the RTC driver to track the number of ticks from the system clock.

f14f9aba41 galileo: Initial support for Intel Galileo Platform
This patch adds the initial support for Intel Galileo Platform. It
contains the minimum set of code required to boot a dummy Contiki
image.

For Galileo initial support, we implemented a linker script, a minimal
bootstrap code, a set of stubbed functions required by newlib, and a
very simple main() function. Moreover, we also define some header files
and macros required by Contiki.

To build applications for this platform you should first build newlib
(in case it wasn't already built). To build newlib you can run the
following command:
$ platform/galileo/bsp/libc/build_newlib.sh

Once newlib is built, you can build applications. To build applications
for Galileo platform you should set TARGET variable to 'galileo'. For
instance, building the hello-world application should look like this:
$ cd examples/hello-world/ && make TARGET=galileo

This will generate the 'hello-world.galileo' file which is a multiboot-
compliant [1] ELF image. This image can be booted by any multiboot-
complaint bootloader such as Grub.

Finally, this patch should be used as a guideline to add the initial
support for others platforms based on x86 SoCs.
