CORExx endstop detection fixes

Browse Source 
1. The CORExx printers were checking more endstop axis than needed.

2. Removed all the CORE_xx_NOT logic.  The motor_direction(xx) routine
always returns the correct data so it is not needed.  It was actually
cause the wrong direction to be checked in some cases.

3. Made the logic/defines for X, Y & Z axis all the same.  The old logic
checked inappropriate configurations for Y and didn't check all the
correct configurations on Z.

4. Added a check for zero steps before the X, Y & Z axis.  Previously
would check the they axis even if there were no movement.
