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

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.
