gpio: Add driver for Altera's PIO core
This driver may handle multiple PIO cores and thus needs to be
setup by calling the altera_pio_init() function within the early
board setup routine.
The driver comes with some extras, see below the copyleft header.

nios2: add gpio support
This patch adds driver for a trivial gpio core, which is described
in http://nioswiki.com/GPIO. It is used for gpio led and nand flash
interface in u-boot.
When CONFIG_SYS_GPIO_BASE is not defined, board may provide
its own driver.
