arm64: dts: rockchip: Fix rt5651 compatible value on rk3399-sapphire-excavator

[ Upstream commit 577b5761679da90e691acc939ebbe7879fff5f31 ]

There are no DT bindings and driver support for a "rockchip,rt5651"
codec.  Replace "rockchip,rt5651" by "realtek,rt5651", which matches the
"simple-audio-card,name" property in the "rt5651-sound" node.

Fixes: 0a3c78e251b3a266 ("arm64: dts: rockchip: Add support for rk3399 excavator main board")
