CCS811 VOC sensor exposes nRESET and nWAKE pins which can be connected to GPIO pins of the host controller. These pins can be used to externally release the device from reset and also to wake it up before any I2C transaction. The initial driver support assumed that the nRESET pin is not connected and the nWAKE pin is tied to ground. This commit improves it by adding support for controlling those two pins externally using a host controller. For the case of reset, if the hardware reset is not available, the mechanism to do software reset is also added. As a side effect of doing this, the IIO device allocation needs to be slightly moved to top of probe to make use of priv data early.
