Lockdep complains about the smu->message_lock mutex being used before
it is initialized through the following call path:
amdgpu_device_init()
amdgpu_dpm_mode2_reset()
smu_mode2_reset()
smu_v12_0_mode2_reset()
smu_cmn_send_smc_msg_with_param()
Move the mutex_init() call to smu_early_init() to fix the mutex being
used before it is initialized.
This fixes the following lockdep splat:
