Subject: [PATCH 0/1] arm64: dts: rockchip: enable SCMI clk for RK3528 SoC

Same as RK3568, RK3528 uses SCMI clk instead of standard ARMCLK.
Add SCMI clk for CPU, GPU and RNG will also use it.

dmesg:
[    0.061333] scmi_core: SCMI protocol bus registered
[    0.125780] scmi_protocol scmi_dev.1: Enabled polling mode TX channel - prot_id:16

[    0.127233] arm-scmi firmware:scmi: SCMI Protocol v2.0 'rockchip:' Firmware version 0x0
