drm/amd/display: Check for null fclk voltage when parsing clock table
[WHY] In cases where a clock table is malformed such that fclk entries have frequencies but not voltages listed, we don't catch the error and set clocks to 0 instead of using hardcoded values as we should. [HOW] Add check for clock tables fclk entry's voltage as well Signed-off-by: Michael Strauss <michael.strauss@amd.com> Reviewed-by: Eric Yang <eric.yang2@amd.com> Acked-by: Rodrigo Siqueira <Rodrigo.Siqueira@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org
