meta-handheld: h3600: support kernel v3.17

This makes the v3.17 kernel work with the h3600 target.

As of kernel v3.17, most drivers for the H3600 have been
upstreamed and we only need two patches to boot it
successfully with full support.

Patch 1 is merged upstream by now (v3.18), patch 2 is
being worked on.
