include: Fixes #1205, C++ usage of sensor.h

I ran into issue #1205 earlier today and realized the fix was to simply
provide the proper casts.  The issue is that C++ is less permissive than
C here, erroring when trying to implicitly convert from `void *` to
`struct gpio_driver_api *`.  The same cast is done in
include/drivers/gpio.h, which is why I did that here as well.

This fix was validated by compiling my C++ application successfully and
also successfully running my app on my board, interacting with sensors.
