soc: rockchip_system_monitor: Add support to set init freq

Browse Source 
As the scmi clk of npu may come from pvtpll, it should power up npu pd
and enable the pclk of pvtpll before set scmi clk. The "assigned-clocks"
in npu node will be set before npu driver probe, at this time the npu
pd may be down, so add "rockchip,init-freq" in opp table node, make
set scmi clk after npu pd is up and pclk of pvtpll is enabled.
