dg1_ctx_workarounds_init() is DG1-only, while
gen12_ctx_workarounds_init() is shared with other platforms. Move the
workaround to the former so there is no additional platform check
needed.

I think you missed the "!" here. I.e., this workaround applies to all
the "gen12" platforms *except* DG1.
oops, thanks for catching that. I'll drop this last patch.
