The following changes where added.
- Removes dependency to slave structure. Selecting a device on the bus only
requires the unique romcode.
- Make search operation mutual exclusive on the bus. This is necessary to
prevent another driver instance from making a transition on the bus at
the same time.
- Skip also rom when only 1 slave is expected on the bus. Physical
connected devuce should be indicated by the maxslave paramter during
initializing, not the reigstered slaves.
- Fixes some compiler warnings in existing ds28e17 driver.

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.
