drm/amd/display: Populate invalid split index to be 0xF
[why]
There exists scenarios where the split index for subvp can be
pipe index 0. The assumption in FW is that the split index
won't be 0 but this is incorrect.
[how]
Instead populate non-split cases to be 0xF to differentiate
between split and non-split.
