MCP4728 consistency & fix ultralcd.cpp

The MCP4728 DAC controls the stepper motor current strenth on the
PRINTRBOARD Rev F and RIGIDBOARD V2 boards.

PR #5792 on 9 FEB 2017 implemented default drive percentages but only on
the RIGIDBOARD V2.

This change moves the default settings to Configuration_adv.h.

Also, ultralcd.cpp won't compile because of a type def conflict.
Changed it to match the one in stepper_dac.cpp
