Fix incorrect rk3399 aclk_vio gating bit, it should be 0, not 10. With
this modification, the aclk_vio_noc should be put into critical list,
since it is required by VOP.
And the Type-C DP need these clocks: aclk_hdcp_noc, hclk_hdcp_noc,
pclk_hdcp_noc. Mark them as critical to avoid someone close them.
