drm/amd/display: Enable DTBCLK DTO earlier in the sequence

[why]
As per programming guide, we need to
enable the virtual pixel clock via DTBCLK
DTO and ungate the clock before we begin
programming OPP/OPTC control registers.
Otherwise, the double-buffered registers
will be left pending until the clocks are enabled.

[how]
Move the DTBCLK DTO programming up to
where we do the legacy DP DTO programming.
