ESP32: Fix xtal 32k not oscillate or oscillate too slowly issue

Browse Source 
ESP32 in revision0 and revision1 uses touchpad to provide
current to oscillate xtal 32k. But revision2 and revision3
do not need to do that.
Note: touchpad can not work and toupad/ULP wakeup sources
are not available when toupad provides current to xtal 32k
