[Why & How]
Correct the gamma 2.2 TF direction used in the supported-TF bitmask
tests. Degam and blnd use DRM_COLOROP_1D_CURVE_GAMMA22 (EOTF
direction); shaper uses DRM_COLOROP_1D_CURVE_GAMMA22_INV (inverse
EOTF direction).
This aligns the tests with commit d8f9f42eff
("drm/amd/display: Fix gamma 2.2 colorop TFs").
