drivers/1wire: add PM hooks and unlink support to sht21 sensor (allowing hot-swappable I2C bus from 1-wire converter)

* drivers/1wire: add PM hook to 1wire bus

* drivers/1wire/ds28e17.c: i2c instance must be zeroed

* drivers/sht21: add unlink support

    Unlike most other unlink implementations in NuttX drivers, this one
    does not allow any I2C operations after unlink, making it possible to
    deallocate the I2C bus.
