iio: accel: adxl367: fix DEVID read after reset

Browse source

regmap_read_poll_timeout() will not sleep before reading,
causing the first read to return -ENXIO on I2C, since the
chip does not respond to it while it is being reset.

The datasheet specifies that a soft reset operation has a
latency of 7.5ms.

Add a 15ms sleep between reset and reading the DEVID register,
and switch to a simple regmap_read() call.
