arm64: dts: rockchip: Remove non-functioning CPU OPPs from RK3576

BugLink: https://bugs.launchpad.net/bugs/2137723

commit 05b80cd1f37db042e074ecc7ee0d39869fed2f52 upstream.

Drop the top-frequency OPPs from both the LITTLE and big CPU clusters on
RK3576, as neither the opensource TF-A [1] nor the recent (after v1.08)
binary BL31 images provided by Rockchip expose those.

This fixes the problem [2] when the cpufreq governor tries to jump
directly to the highest-frequency OPP, which results in a failed SCMI call
leaving the system stuck at the previous OPP before the attempted change.
