galileo: Add BSP files

This patch creates the platform/galileo/bsp directory. This directory
contain all files related to Galileo's Board Support Package (BSP). For
now, the BSP consists of libc and bootloader.

Within the BSP directory, we have the scripts build_newlib.sh and build_
grub.sh. These scripts provide an easy and quick way to build the newlib
and the grub for the Galileo platform.
