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
[    0.126628] arm-scmi firmware:scmi: SCMI Notifications - Core Enabled.
[    0.127233] arm-scmi firmware:scmi: SCMI Protocol v2.0 'rockchip:' Firmware version 0x0

CPU frequency: ~# mhz
count=611657 us50=19994 us250=99945 diff=79951 cpu_MHz=1530.080

Changes in v3:
  Remove unnecessary assigned-clocks

Changes in v2:
  Change sram to reserved-memory
