    gen8: Fix the YUV->RGB shader

    Use the correct register (Yn_01) with first half of the
    Y samples instead of using the register (Yn_23) with the
    second half twice when computing the green channel.

    Also use the Yn_01 register name instead of Yn for the red
    channel as well, just for a bit of extra consistency.
