drm/amdgpu/powerplay: using the FCLK DPM table to set the MCLK

Browse Source 
commit 022ac4c9c5 upstream.

1.Using the FCLK DPM table to set the MCLK for DPM states consist of
three entities:
 FCLK
 UCLK
 MEMCLK
All these three clk change together, MEMCLK from FCLK, so use the fclk
frequency.
2.we should show the current working clock freqency from clock table metric
