arm64: dts: rockchip: Enable GPU on rk3588-evb1

Browse Source 
Enable the Mali GPU in the RK3588 EVB1.

This marks the GPU regulators as always-on, because the generic
coupler regulator logic from the kernel can only handle them
when they are marked as always-on. Technically it's okay to
disable the regulators, when the GPU is not used.

Considering the RK3588 EVB1 is not battery powered, the slightly
increased power consumption for keeping the regulator always
enabled is not a big deal. Thus it's better to enable GPU support
than wait for a better solution.
