rockchip: chromebook_speedy: Enable sound

Commit ec107f04b619 ("rockchip: chromebook_minnie: Enable sound") and
commit 2d0c01b8f0ad ("sound: rockchip: Add sound support for jerry")
enable audio support for chromebook_minnie and chromebook_jerry. Enable
it for chromebook_speedy as well, but put the non-upstream sound node
in the board -u-boot.dtsi instead.
