Add power-gpios device-tree binding property to power on module before
communicating with it. This pin is called CHIP_PU in case of ESP32{,-S2}
and CHIP_EN in case of ESP8266. Dedicated reset pin is available only on
the latter, however Espressif recommends (in ESP8266 Hardware Design
Guidelines) to use CHIP_EN instead. Follow those recommendations and use
power-gpios to reset chip if that is provided over device-tree.
Configure power-gpios and reset-gpios as inactive by default, so that
chip becomes ready after executing esp_reset() function, either if one
or both are provided over device-tree.
