Remove the binding for the generic Mercury+ AA1 on PE1 carrier board.

The removed Mercury+ AA1 on PE1 carrier board is just a particular
setup case, which is actually replaced by the set of generic Mercury+
AA1 combinations patch.

In other words a combination of a Mercury+ AA1 on a PE1 base board,
with boot mode SD card is already covered by the generic AA1
combinations. There is no further reason to keep this particular case
now in a redundantly. Thus the redundant DT setup is removed.
