mcu: Do not invert the direction of pullup pins by default

A pullup setting on an input pin (ie, '^') should enable the hardware
pullup resistor, but it should not invert the trigger level (ie, it
should remain trigger on high).  Those that need to change the trigger
level (ie, trigger on low) must now do that explicitly (ie, '^!').
This makes the code match what other firmwares do.
