Yongqiang Sun 6f29c3588b drm/amd/display: Add unknown clk state.
[Why]
System hang during S0i3 if DP only connected due to clk is disabled when
doing link training.
During S0i3, clk is disabled while the clk state is updated when ini_hw
called, and at the moment clk is still disabled which indicating a wrong
state for next time trying to enable clk.

[How]
Add an unknown state and initialize it during int_hw, make sure enable clk
command be sent to smu.
