drm/amd/pm: smu_v14_0_0: fix DCLK metric reporting via VCLK level index

Browse source

SmuMetrics_t has no DclkFrequency field but DCLK and VCLK have
separate DPM clock tables with different frequencies at each level.

Introduce smu_v14_0_0_find_clk_level(), a shared helper that
finds the closest DPM level for a given target frequency in a
frequency array.

For METRICS_AVERAGE_DCLK, use the helper to find the DPM level
whose VCLK frequency matches the reported VclkFrequency and
return the DCLK frequency at that same level index, since both
clocks share the same level count (VcnClkLevelsEnabled /
Vcn0ClkLevelsEnabled).

The original code returned 0 for METRICS_AVERAGE_DCLK, which broke
the active-level marker in pp_dpm_dclk entirely.
