Browse source 
This commit updates the voltages of each brownout level in Kconfig.
Note that there is some variation of brownout voltage between each chip.

The brownout detector will reset the chip when the supply voltage is below this level.
The brownout detector will reset the chip when the supply voltage is approximately
below this level. Note that there may be some variation of brownout voltage level
between each ESP32 chip.
#The voltage levels here are estimates, more work needs to be done to figure out the exact voltages
#of the brownout threshold levels.
