dt-bindings: iio: pressure: add honeywell,hsc030

Adds binding for digital Honeywell TruStability HSC and SSC series
pressure and temperature sensors.
Communication is one way. The sensor only requires 4 bytes worth of
clock pulses on both i2c and spi in order to push the data out.
The i2c address is hardcoded and depends on the part number.
There is no additional GPIO control.
driver is based on iio/togreg
