[PATCH v2025.09.y 04/49] ARM: dts: rockchip: Set initial CPU frequencies for RK3588

[Ahmad Fatoum]

From: Alexander Shiyan <eagle.alexander923 at gmail.com>

During system boot, the cpufreq driver reports unlisted initial frequencies:
cpufreq: cpufreq_policy_online: CPU0: Running at unlisted initial frequency: 900000 kHz, changing to: 1200000 kHz
cpufreq: cpufreq_policy_online: CPU4: Running at unlisted initial frequency: 816000 kHz, changing to: 1200000 kHz
cpufreq: cpufreq_policy_online: CPU6: Running at unlisted initial frequency: 816000 kHz, changing to: 1200000 kHz

Add assigned-clock-rates to the SCMI clock controller node in the device
tree to establish proper initial frequencies.
This ensures all CPU cores boot at valid frequencies that match the
cpufreq policy, eliminating the warning messages and unnecessary
frequency changes during initialization.
