TM4C123G LaunchPad:  Add initialization logic for an external AT24 EEPROM.  This is intended only to suppport testing of the Tiva I2C driver

Nucleo-f402re: Add an option to use only a minimal set of joystick buttons.  This eliminates some GPIO conflicts

Nucleo-F4x1RE: Add support for an analog joystick shield.  There are still some ADC issues to be worked through as of the initial commit
