[PATCH 07/13] clk: samsung: gs101: mark PERIC0 IP TOP gate clock as critical

Testing USI8 I2C with an eeprom revealed that when the USI8 leaf clock
is disabled it leads to the CMU_TOP PERIC0 IP gate clock disablement,
which then makes the system hang. To prevent this, mark
CLK_GOUT_CMU_PERIC0_IP as critical. Other clocks will be marked
accordingly when tested.
