624a60f456 drivers/1wire: Adds some improvents
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.

3cf830bd67 Merged in juniskane/nuttx_stm32l4/1wire_sht21_changes_pr (pull request #631)
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.
