Fix GPIO and remove unused ones from Romulus.py

1. Remove unused GPIO configs;
2. Add comments of GPIO names in schematic for CRONUS_SEL,
   POWER_BUTTON, RESET_BUTTON;
3. Fix the GPIO configs for BMC_THROTTLE, IDBTN;

The GPIO names are hard-coded for now and some of them conflict with P8.
A future task will abstract the GPIO names so we can use names in schematic.
Once the task is done, this file will be updated to use GPIO names in
schematic.
