star: Initialize AIF2 registers to same values as GB

From the old nvodm codec config, GPIOs 1,2 and 6 are supposed to
be logic level input switches:

        NvU32 reg700 = 0xa101;
        NvU32 reg701 = 0xa101;
        NvU32 reg702 = 0x8100;
        NvU32 reg703 = 0x8100;
        NvU32 reg704 = 0x8100;
        NvU32 reg705 = 0xa101;
        NvU32 reg706 = 0x0100;
