According to the pd blocks, VIO1_NIU is required by RGA,ISP and VOP1. Then at least one VIO_NIU should be turned on to supply eDP, HDMI, MIPI.
If eDP,HDMI,MIPI is inited early than VOP or RGA is inited early than VOP1, system will hang.
So make aclk_vio1_niu a critical clock and turn it on at all times.
