arm64: dts: rockchip: Split GPU OPPs of RK3588 and RK3588j

Browse Source 
RK3588j uses a different set of OPPs for its GPU, both in terms of
allowed frequencies and in terms of voltages.

Move the GPU OPPs table into per-variant .dtsi files to accommodate
for this difference.

The table for RK3588j is adapted from Rockchip downstream sources [1],
while RK3588 one is moved verbatim into the per-variant .dtsi file.
The values provided for RK3588 in the downstream sources match those
in the original commit.
