drm/mediatek: Fix CCORR mtk_ctm_s31_32_to_s1_n function issue
if matrixbit is 11,
The range of color matrix is from 0 to (BIT(12) - 1).
Values from 0 to (BIT(11) - 1) represent positive numbers,
values from BIT(11) to (BIT(12) - 1) represent negative numbers.
For example, -1 need converted to 8191.
so convert S31.32 to HW Q2.11 format by drm_color_ctm_s31_32_to_qm_n,
and set int_bits to 2.
