wandboard: Add Alfonso Tames as maintainer

Please add me as maintainer for the Wandboards. For now, I can test
only the Wandboard Quad and Wandboard Dual boards but not the
Wandboard Solo since I do not have access to that board.

linux-wandboard: Update to 3.10.31-1.1.0 beta2 based kernel

This updates the Wandboards' kernel to 3.10.31-1.1.0 beta2 to be in
line with Yocto's next 1.8 release. This commit also drops kernel
3.10.17 support since the new GPU drivers from Freescale do not
support this or older kernel versions.
