Jonathan Cameron 6a15fef2cb iio:pressure: drop assign iio_info.driver_module and iio_trigger_ops.owner

Peter Meerwald a2d8be6823 iio: Add t5403 barometric pressure sensor driver 
16-bit pressure and temperature sensor

the chip can do I2C and SPI, only the I2C interface is supported
by the driver at the moment
