8.4.1.55 Video Processor Chrominance 4-tap Poly-phase Filter Coefficients (VP_POLY4_C0_LL, R/W,
Address = 0xF910_012C)
Unlike VP_POLY4_Y registers, there are only a half of the coefficient registers for horizontal Chroma Scaler. The
coefficients are assumed to be symmetric so that only half of them are kept. Some parts of them are unsigned
integer and the other parts are signed integer. You must be careful while setting them.
