clk: samsung: gs101: gpio_peric0_pclk needs to be kept on

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.
