As discussed in [0], the Rockchip power domain driver does not consider
the external supplies (such as VDD_GPU on the RK3568 EVB1). In the scope of
this discussion it has been pointed out that turning this voltage on/off
on the fly is not explicitly supported. This patch follows the other RK356x
boards by example and sets the vdd_gpu regulator to always on.
