We should avoid having multi-function APIs. It should be up to the caller

Those gfxoff controls added for some specific ASICs are unnecessary.
The functionalities are not affected without them. Also to align with
other ASICs, they should also be dropped.

Those implementation details(whether swsmu supported, some ppt_funcs supported,
accessing internal statistics ...)should be kept internally. It's not a good
practice and even error prone to expose implementation details.

amdgpu_pm.c holds all the user sysfs/hwmon interfaces. It's another
client of our power APIs. It's not proper to spike into power
implementation details there.
