VL53L0X_PerformSingleRangingMeasurement() returns a signed 8-bit
integer, not an unsigned 8-bit integer, making the "< 0" comparison
worthless.

The I2C address of vl53l0x are write in hex, but the VL53L0X_I2C_ADDR
type is int.
Fix this by replace "int" with "hex".

It makes no sense to set the restart condition flag on a first message
and some i2c bus drivers (like the stm32 v1 driver) actually reject
them by returning an error from i2c_transfer().
This patch fixes that by using i2c_burst_read() in tmp112_reg_read()
instead. For consistency, tmp112_reg_write() is also changed to use
i2c_burst_write().

I have been using this the TMP112 driver with success with a TMP102
connected to to nucleo-f411re board (via I2C1 using PB8/9).
According to the datasheets, both devices are both driver and pin
compatible although the TMP102 is less accurate.
This temperature sensor is not a thermopile sensor type as stated in
comments.
This patch updates that help info

Add support for AMS CCS811 Digital Gas Sensor for monitoring
indoor air quality. This sensor reports the following parameters:
1. Co2 concentration
2. VOC concentration
3. Sensor voltage
4. Sensor current
This driver only supports polling mode as of now.

Most of sensor channels defined by Zephyr use the main, unscaled
SI unit. We also have SENSOR_CHAN_ALTITUDE which is defined in
meters. So, it only makes sense to define distance in meters too
The only driver supporting SENSOR_CHAN_DISTANCE as of now is
vl53l0x.c, which was updated accordingly. Also, update doc links
in the driver based on the review comment.

Based on the discussion in #5693, the reason why humidity was defined
in milli-percent was likely following Linux which defines it as such
in its sensor subsystem:
http://elixir.free-electrons.com/linux/latest/source/Documentation/ABI/testing/sysfs-bus-iio#L263
However, Linux defines temperature in milli-degrees either, but
Zephyr uses degrees (similarly for most other quantities). Typical
sensor resolution/precision for humidity is also on the order of 1%.
One of the existing drivers, th02.c, already returned values in
percents, and few apps showed it without conversion and/or units,
leading to confusing output to user like "54500".
So, switching units to percents, and update all the drivers and
sample apps.
For few drivers, there was also optimized conversion arithmetics
to avoid u64_t operations. (There're probably more places to
optimize it, and temperature conversion could use such optimization
too, but that's left for another patch.)

Move to new Kconfig pattern in which we use an if !HAS_DTS_I2C_DEVICE
block for the Kconfig symbols that can now come from DT generation.
This pattern is useful to allow us to define default values for the
generated symbols for build-all testing.

The generic library provided by ST in ext/hal/st/lib/sensor/vl53l0x
needs to be adapted to the platform. In this case, the main
modification is the way to use I2C. This is now using the Zephyr

Add driver for ST vl53l0x time of flight sensor.
This driver can be used in 2 modes :
* proximity sensor :
configure VL53L0X_PROXIMITY_THRESHOLD
will return 1 if target is between sensor and threshold,
else, 0
* distance sensor :
will return the distance in millimeters from sensor to target
This driver use the official STMicroelectronics library for vl53l0x.

This patch adds the driver for Panasonic AMG88xx
infrared array sensor.
The driver was developed within the framework of a student
