[PATCH v4 06/11] iio: amplifiers: ad8366: replace reset-gpio with reset controller

[Rodrigo Alencar via B4 Relay]

From: Rodrigo Alencar <rodrigo.alencar@xxxxxxxxxx>

Remove reset_gpio from the device state struct and use the
reset_control interface instead, using a local variable,
as it is not being used anywhere else.
