aco: disable sdwa on gfx11
Instead of SDWA v_mov_b32/v_xor_b32, we can use a combination of
v_add_u16/v_sub_u16 (add/sub swap, similar to xor swap) and v_perm_b32
with a literal.
I don't know yet if GFX11 adds any new instructions which makes this
easier, but this approach should have full functionality.
