drm/amd/pm:restate all customized OD features on every table upload for smu 13.0.0/smu 14.0.2
PMFW interprets OverDriveTable.FeatureCtrlMask as the complete set of overdrive features that are currently overridden, not as a delta describing the operation at hand. On import it resets every feature whose bit is clear back to its default value - for the VF curve that means zeroing VoltageOffsetPerZoneBoundary[] outright. The driver assumed the opposite. smu_v14_0_2_od_edit_dpm_table() clears the mask after a successful commit, so a subsequent above-default power1_cap write goes through smu_v14_0_2_set_ppt_limit() and uploads a table carrying only PP_OD_FEATURE_PPT_BIT. PMFW then drops the user's voltage offset and reverts to the stock V/F curve, while the driver's cached user table still reports the offset through pp_od_clk_voltage.
