Subject: [PATCH v3 0/2] send message to pmfw when SMT changes

When the CPU SMT changes on the fly, send the message to pmfw
to notify the SMT status changed.

Changes in v3
1./ Because it is only required for Vangogh, move registering notifier
to vangogh_ppt.c, then remove the patch 2, and the number of patches
decreased to 2.

Changes in v2:
1/. Embed the smt notifer callback into "struct smu_context" structure.
2/. Correct the PPSMC_Message_Count value.
3/. Improve several code styles and others.

Wenyou Yang (2):
  cpu/smt: add a notifier to notify the SMT changes
  drm/amd/pm: vangogh: send the SMT enable message to pmfw
