gallium/ttn: partial fix for output arrays 

It isn't quite yet practical to enable TGSI_ANY_INOUT_DECL_RANGE shader
cap yet, at least not in drivers that need lower_to_scalar pass (which
right now is all of the ttn users), since the register arrays do not get
converted to SSA, which angers nir_lower_alu_to_scalar.
