Ricardo de Almeida Gonzaga 93c7988069 x86: Add Galileo pinmux support
This patch adds the galileo-pinmux.c and galileo-pinmux.h files,
which support access to pinmux configuration through a function
interface.

This is not 100% supported yet due to some pinmux paths
need Quark X1000 GPIO (legacy and non-legacy) configurations.

After we finish to implement Quark X1000 GPIO driver we'll add
support for this.
