display: hk3: remove the vblank delay while setting higher op_hzandroid-14.0.0_r0.8android-gs-shusky-5.15-android14-d1
Waiting for a vblank cannot make sure we don't have frame transfer
after switching to higher op_hz. Raise BTS instead.
Bug: 284094183
Test: switch to higher op_hz and capture trace
