This patch change the power registers reading from average to maximum.
If SMU team verifies it, I am OK with it.

pkgpwr is the average gpu power of 100ms. it is calculated by
firmware in real time.
1. we can send smu message PPSMC_MSG_GetCurrPkgPwr to read currentpkgpwr
directly.
2. On Fiji/tonga/bonaire/hawwii, without PPSMC_MSG_GetCurrPkgPwr support.
Send PPSMC_MSG_PmStatusLogStart/Sample to let smu
with this patch, there should be no difference between AGT and sysfs.

Sampling period is too short. The power reading value will be not
aligned with AGT's. It will confuse user that why AMD provides two
different power results.

Send PPSMC_MSG_PmStatusLogStart to let smu write currentpkgpwr
to ixSMU_PM_STATUS_94. this is asynchronous. need to delay
