drm/amd/pm: add SMU multi-msgs helpers

Browse source

SMU15 driver messages can carry multiple input parameters and return
values, but callers still have to build struct smu_msg_args directly.

Add common SMU multi-msgs helpers in smu_cmn and reuse them in the
single-parameter wrapper and the shared table transfer path.

Keep smu_cmn_send_smc_msg() semantics unchanged for older callers.

No functional change intended.
