iwlwifi/rtw88: re-attach to build after updates

While the build-breaking changes were only in the window of
the two commits, further updates were easier to merge and
restored some functionality as well. Now that we are done,
add iwlwifi/rtw88 back to the build.

This reverts commit b75d1ce6c10652fc4bfbf509deeae0e05c3d1356.
