manta: senors: add HAL for light and pressure sensors

This HAL supports sensors using Industrial I/O subsystem.
These sensor devices will be located in /sys/bus/iio/devices.

Light Sensor:
    IIO device name: lightsensor-level
    chan_type: IIO_LIGHT
    channel: in_illuminance0_input
    event: /dev/iio:device? (assigned dynamically)

Pressure Sensor:
    IIO device name: barometer
    chan_type: IIO_PRESSURE (This is not yet defined in main stream.)
    channel: in_pressure0_input
    event: /dev/iio:device? (assigned dynamically)

TODO: iio/events.h and iio/types.h should be moved to
    external/kernel-headers/original.
