- Add TinyMemBenchNX, a simple memory benchmark program based on [tinymembench](https://github.com/ssvb/tinymembench)

- Sys-clk Fix: Ignore RAM clock values in config, or sys-clk will stuck in a loop of resetting RAM clocks (generating huge log file and degrading performance)

- Fix: Temporary frequency override in sys-clk overlay/manager
