We want to use backported modules this means we need to make
some thing a module for it to work. Take Daniel's .config file,
run make savedefconfig and update our defconfig.

We actually only use the PMIC (TPS65910) RTC in the hardware,
and not the AM335x RTC. Having a driver for a hardware that doesn't
receive actual backup voltage doesn't make sense.
This currently requires the meta-ti layer but we will make sure
that nothing from it will be required in the end. The kernel is
based on linux-3.2 as this is the "default" TI kernel that supports
the SGX (not that we care)
