target-mips: Fix helper and tests for dot/cross-dot product instructions

Browse source 
Helper function for dpa_w_ph, dpax_w_ph, dps_w_ph and dpsx_w_ph incorrectly
defines halfword vector elements as unsigned values. This results in wrong
output which is not triggered in the tests as they also follow this logic.
