clk: samsung: gs101: fix synchronous external abort in samsung_clk_save()
commit f2052a4a62465c0037aef7ea7426bffdb3531e41 upstream.
EARLY_WAKEUP_SW_TRIG_*_SET and EARLY_WAKEUP_SW_TRIG_*_CLEAR
registers are only writeable. Attempting to read these registers
during samsung_clk_save() causes a synchronous external abort.
Remove these 8 registers from cmu_top_clk_regs[] array so that
system suspend gets further.
Note: the code path can be exercised using the following command:
echo mem > /sys/power/state
