trusty: add more tracepoints around smc8 call.android-14.0.0_r0.8android-14.0.0_r0.18android-gs-shusky-udc-d1android-gs-shusky-5.15-android14-d1android-gs-shusky--udc-d1
trusty_transfer_memory itself can make multiple smc8 calls with
different perimeters. We add tracepoints to breakdown more if any
particular smc8 calls are taking a long time and if so to record their
argument perimeters.
