esp32/boards: Use auto xtal freq config instead of default 40MHz.

Browse Source 
Auto-detection of the crystal frequency is convenient and allows for a
single binary for many different boards.  But it can be unreliable in
certain situations so in production, for a given board, it's recommended to
configure the correct fixed frequency.
