Likun Gao 76d8f83b2a drm/amdgpu/powerplay: unify smu send message function 
Drop smu_send_smc_msg function from ASIC specify structure.
Reuse smu_send_smc_msg_with_param function for smu_send_smc_msg.
Set paramer to 0 for smu_send_msg function, otherwise it will send
with previous paramer value (Not a certain value).
Materialize msg type for smu send message function definition.
