Thomas Chou 1e8e9bad2d nios2: add gpio support to nios2-generic board 
This patch adds gpio support of Altera PIO component to the
nios2-generic board. Though it drives only gpio_led at the
moment, it supports bidirectional port to control bit-banging
I2C, NAND flash busy status or button switches, etc.
