This allows requests (via the DTS) for PCLK_HDMI_CTRL/PCLK_VIO_GRF, which are clock gates in the HDMI output path for the RK3399. As these are enabled by default (i.e. after reset), we don't implement any logic to actively open/close these clock gates and simply assume that their reset-default has not been changed.
