dt-bindings: qcom,hv-haptics: add qcom,hbst-ovp-trim property

Browse Source 
Add qcom,hbst-ovp-trim property as an option for SW to trigger hBoost
OVP trim sequence. The sequence adjusts certain trim registers and
reduces hBoost voltage stepper rate. The adjustment can help in preventing
hBoost overshoots that might trigger OVP and potentially lead to the
shutdown of haptics driver.
