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.
