Use pseudomodules to add a dependency on the relevant feature:
periph_spi if the abp2_spi pseudomodule is selected,
or periph_i2c if the abp2_i2c pseudomodule is selected.
Honeywell ABP2 pressure sensors series.
Implement all sensors features, only supporting the SPI version
of the sensor.
Prepare future support for the I2C interface by emphasizing where
to implement the code that will support the I2C bus version.
