mb/google/dedede/var/drawcia: Configure Acoustic noise mitigation UPDs
Enable Acoustic noise mitigation for drawcia and set slew rate to 1/4 which is calibrated value for the board. Other values like PreWake, Rampup and RampDown are 0 by default.
BUG=b:162192346 BRANCH=dedede TEST=Correct value is passed to UPD and Acoustic noise test passes.
