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.

v3: split patches for gpio and spi, based gpio on altera pio core. v2: remove mmc_spi_init()

This will build a u-boot image that will not work with any of the standard configurations ... correct? ... since the GPIO component is custom (not supplied by the vendor)?
