drm/amd/pm: smu_v14_0_0: add SMU_DCEFCLK support in DPM frequency queries

Browse source

Add SMU_DCEFCLK case to smu_v14_0_1_get_dpm_freq_by_index and
smu_v14_0_0_get_dpm_freq_by_index using DcfClocks[] with
NumDcfClkLevelsEnabled bounds check. Add matching case in both
get_dpm_level_count functions.

Add SMU_DCEFCLK case in emit_clk_levels to list DCEF DPM levels.
No * marker is emitted since SmuMetrics_t has no DcfclkFrequency
field (same firmware limitation as Phoenix).

Without this, pp_dpm_dcefclk reports N/A on Strix Halo.
