xpedite1k: Add support for additional GPIO pins
Enable GPIO pins for an I2C EEPROM write protect, a system reset pin, and a PMC #MONARCH pin. These pins are not currently used in U-Boot, but are used in OSes and may be used in U-Boot in the future. Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Stefan Roese <sr@denx.de>
