drm/amd/display: Move DPM clk read to clk_mgr_construct in DCN42

Browse source

[Why&How]
The DPM clocks on DCN42 are currently read on every dm_resume, which can
cause in gpu memory freeing while the device is still in suspend.

Move the DPM clock read functionality to clk_mgr_construct() so it
completes once on driver enablement.
