RETIMER_REDRIVER_INFO shows the buffer as a decimal value with a '0x' prefix, which is somewhat misleading. Fix it to print hexadecimal, as was intended.

Amgpu's backlight update status function was returning 1 (an error value) when the backlight property was 0. This breaks users that assume 0 is a valid backlight value (which is a correct assumption) If the user passes in a backlight value of 0, tell them everything is fine, then write a value of 1 to hardware.

[Why] When going to full-screen mode commit_planes_for_stream tries to decrease dcf_deep_sleep value, but safe_to_lower is false, so we don't send the new value to SMU but dc context gets updated. Later when dc_post_update_surfaces_to_stream tries to lower dcf_ds when safe_to_lower is true, this check prevents the message from being sent. [How] Remove the check that compares new value with what is stored in dc_context. This check is not necessary as dcn1_update_clocks already checks if the value is different from the current dcf_dp value. Signed-off-by:

[Why] In DCN we want direct DC to SMU calls, with minimal interference from pplib. The reason for each pp_smu interface mapping to 1 SMU message is so we can have the sequencing of different SMU message in DC and shared across different OS's. This will also simplify debugging as DAL owns this interaction and there's no confusion about division of ownership. [How] Part 4: Change clock units so they match the values PPLib sends to SMU.
