YRabbit 4d5c48ad83 Gowin. Fix DSP MULT36X36
When multiplying 36 bits by 36 bits using four 18x18 multipliers, the
sign bits of the higher 18-bit parts of the multipliers were correctly
switched, but what was incorrect was leaving the sign bits of the lower
parts of the multipliers uninitialized. They now connect to VSS.
