Subject: [PATCH v5 8/8] arm64: dts: rockchip: Split GPU OPPs of RK3588 and
RK3588j
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.

Fixes: 6fca4edb93d3 ("arm64: dts: rockchip: Add rk3588 GPU node")
