drm/amd/display: Add fallback to prefetch mode 1 if 0 fails
[Why]
In some cases, prefetch mode 0 is unsupported but prefetch 1 is
supported. Due to previous change always forcing prefetch mode to 0, we
are failing bandwidth validation in cases where we should not.
[How]
By default try prefetch mode 0 but in the case validation fails, attempt
to do prefetch mode 1 to see if it is supported.
