drivers/sensor: add support to LPS28DFW pressure sensor

The LPS28DFW is an ultracompact, piezoresistive, absolute pressure sensor.
Compared to the LPS22DF, the LPS28DFW is waterproof and has a Dual FS
capability and does not have SPI. This commit extends the LPS22DF driver to
be compatible with the LPS28DFW device.
