drm/amd/display: Fix unintialized max_bpc state values
[Why]
If the "max bpc" isn't explicitly set in the atomic state then it
have a value of 0. This has the correct behavior of limiting a panel
to 8bpc in the case where the panel supports 8bpc. In the case of eDP
panels this isn't a true assumption - there are panels that can only
do 6bpc.
Banding occurs for these displays.
[How]
Initialize the max_bpc when the connector resets to 8bpc. Also carry
over the value when the state is duplicated.
