If you did:
si_pm4_set_reg(pm4, reg, val0);
si_pm4_cmd_add(pm4, val1);
si_pm4 set_reg(pm4, reg + 4, val1);
it wrote val0 to reg, val1 to reg + 4, and val2 to reg + 8.
This fixes it by clearing last_opcode in si_pm4_cmd_add, so that
si_pm4_set_reg doesn't try to combine set_reg calls across si_pm4_cmd_add.
Fixes: da78d50bc8 - radeonsi: make si_pm4_cmd_begin/end static and simplify all usages
