redbear-mini: drop duplicate 30_cpufreqd (double-run + buries login prompt)

cpufreqd was started twice: 15_cpufreqd (redbear-device-services.toml, early)
and a redundant 30_cpufreqd here (at getty time). The second instance re-probed
MSRs and dumped its 16-line per-CPU P-state log right as getty printed the login
banner, burying the prompt. Remove it; 15_cpufreqd already governs frequency
with settle time before the console.
