This pclk clock is required any time we access the pinctrl registers of this block. Since pinctrl-samsung doesn't support a clock at the moment, we just keep the kernel from disabling it at boot, until we have an update for pinctrl-samsung to handle this required clock, at which point we'll be able to drop the flag again.
