drm/nouveau/kms/tu102-: disable input lut when input is already FP16
On Turing, an input LUT is required to transform inputs in fixed-point
formats to FP16 for the internal display pipe. We provide an identity
mapping whenever a window is enabled for this reason.
HW has error checks to ensure when the input is already FP16, that the
input LUT is also disabled.
