2020-01-07amd/amdgpu/sriov enable onevf mode for ARCTURUS VFJack Zhang
Before, initialization of smu ip block would be skipped for sriov ASICs. But if there's only one VF being used, guest driver should be able to dump some HW info such as clks, temperature,etc. To solve this, now after onevf mode is enabled, host driver will notify guest. If it's onevf mode, guest will do smu hw_init and skip some steps in normal smu hw_init flow because host driver has already done it for smu. With this fix, guest app can talk with smu and dump hw information from smu. v2: refine the logic for pm_enabled.Skip hw_init by not changing pm_enabled. v3: refine is_support_sw_smu and fix some indentation issue.

On navi10, the SMU code ignored the power percentage overdrive setting entirely, and would not allow you to exceed the default power limit at all.
