[PATCH] Add 520MHz opp node to RK3326's dtsi

[Maccraft123]

From: Maciej Matuszczyk <maccraft123mc at gmail.com>

According to Rockchip's BSP, RK3326's GPU can go faster than 480MHz
This was missed when gpu_opp_table node was added in
commit f43e351c9630 ("arm64: dts: rockchip: Add gpu opp nodes to px30 dtsi")

The values in rk3326.dtsi match Rockchip's kernel,
but Odroid-GO Advance's kernel sources point at different microvolt
value, that has to be overridden in board dts.
