The patch we were using comes from the time during dualboot support development
where said feature was selectable at build time. The patch adds a new build
option, giving the impression that it only gets enabled under certain
circumstances, when in reality:
* The option is never enabled anywhere in our code
* It's a string option that is treated like a boolean, meaning its
respective conditional compilation is always getting compiled even when
disabled
Our current dualboot support is enabled at runtime, so it doesn't make sense to
have a build-time option related to it, especially one that's broken. Replace
the patch with a functionally equivalent one that is less confusing. Also,
remove the related config option from our defconfig.
