[PATCH 4/4] arm64: dts: rockchip: add OPPs for rk3368-lion

This adds CPU operation points for the RK3368. We only add them to the
the RK3368-uQ7 SoM (Lion) because patches for the SoC where reverted
in the past.
commit 6354a06cbaa8 ("Revert "arm64: dts: rockchip: Add basic cpu
frequencies for RK3368"")
