[PATCH v5 7/8] arm64: dts: rockchip: Add OPP data for CPU cores on RK3588j

[Alexey Charkov <alchark@gmail.com>]

RK3588j is the 'industrial' variant of RK3588, and it uses a different
set of OPPs both in terms of allowed frequencies and in terms of
applicable voltages at each frequency setpoint.

Add the OPPs that apply to RK3588j (and apparently RK3588m too) to
enable dynamic CPU frequency scaling.

OPP values are derived from Rockchip downstream sources [1] by taking
only those OPPs which have the highest frequency for a given voltage
level and dropping the rest (if they are included, the kernel complains
at boot time about them being inefficient)
