Now that we only list features of interest to kernel space, lots of GPUs have the same feature bits. To cut down on the repetition in the file, merge feature lists that are identical between similar GPUs. Note that this leaves some unmerged identical Bifrost feature lists, as there are more features affecting Bifrost kernel space that we do not yet handle.
