chaijie a48b5246cc ESP32: Fix xtal 32k not oscillate or oscillate too slowly issue
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

esp_hw_support

This component contains hardware-related operations for supporting the system. These operations are one level above that of hal in that these(1) use system services such as memory allocation, logging, scheduling or (2) may be multi-step operations involving/affecting multiple parts of the SoC.

Implementations that don't fit other components cleanly, but are not worth creating a new component for (yet) may also be placed here as long as they don't pull dependencies other than the core system components.
