drm/radeon/kms: adjust default clock/vddc tracking for pm on DCE5
NI chips no longer load the MC ucode in the asic_init sequence so the asic comes up in a basic mode with low engine/memory clocks and a voltage. Once the MC ucode is loaded by the driver the card can be programmed to it's proper default clocks and voltage. As such the default clocks in the firmware info table as the post clocks, not the default running clocks. Track the default post clocks and default running clocks separately to handle this.
