PCF8574 pin name duplication

[Richard Sewell]

I've just stumbled over what looks like a little copy-and-paste bug - in

https://github.com/Datenheld/Bulldog/blob/Version-0.1.0/bulldog.devices/src/main/java/org/bulldog/devices/portexpander/PCF8574.java

there are three pins with the same name:

public static final String P5 = "P5";

public static final String P6 = "P5";

public static final String P7 = "P5";

Thanks for an awesome library, by the way!
