arm64: dts: rockchip: don't set cpll rate for Odroid Go

The Odroid Go Advance devicetree tries to set the rate for the cpll
clock to 17MHz, which is not a supported rate. This fails, and triggers
the error of "clk: couldn't set cpll clk rate to 17000000 (-22),
current rate: 17000000" in the dmesg log. Remove the incorrect rate.
