at91: add 4.4 support

This puts the existing patches and config in a 3.18 folder and introduces
a 4.4 config and patches.
The USB clock fix patch is no longer necessary, and the patches applying
to non DT boards has been dropped as the platform has been converted.
4.4 config was generated by copying 3.18 and running make kernel_menuconfig,
scripts/kconfig.pl filled in the gaps.
