arm64: dts: meson: remove CPU opps below 1GHz for SM1 boards
stable inclusion from stable-v5.10.114 commit 70d2df257eed77aba55b124751ab98b3510216dd category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5IY1V Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=70d2df257eed77aba55b124751ab98b3510216dd -------------------------------- [ Upstream commit fd86d854 ] Amlogic SM1 devices experience CPU stalls and random board wedges when the system idles and CPU cores clock down to lower opp points. Recent vendor kernels include a change to remove 100-250MHz and other distro sources also remove the 500/667MHz points. Unless all 100-667Mhz opps are removed or the CPU governor forced to performance stalls are still observed, so let's remove them to improve stability and uptime.
