When the SMT changes on the fly, send the message to the PMFW to notify the SMT status changed. Changes in v6 1./ Update last_smt_active only when the return from smu_set_cpu_smt_enable() successfully. 2./ Use smu->adev->pm.fw_version to check smu version, if it is not assigned, get the smu version and assigned it. 3./ Remove the redundant error message print. Changes in v5 1./ Add a new vangogh_fini_smc_tables() to accommodate the timer fini and smu_v11_0_fini_smc_tables(). 2./ Move the version check of SMU version before initializing the timer. Changes in v4 1./ Since we didn't find a good solution to handle the case that manually offlining all the SMT siblings using /sys/devices/system/cpu/cpu*/online to disable or enable SMT. Come up with a new solution, add a timer to poll the SMT state periodically, if finding that the SMT state is changed, it invokes the interface to notify the PMFW. 2./ Move the generic code to smu_cmn.c. 3./ Add PMFW version check for this feature. 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.
