6aa9c3a68f cleanup: include/: move gpio.h to drivers/gpio.h 
move gpio.h to drivers/gpio.h and

No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.

e84d1a4f31 drivers: gpio: Nios-II: Fix condition on gpio_nios2_config_oput_port() 
(flags & GPIO_DIR_IN) is always zero because GPIO_DIR_IN is 0, then
we have to use GPIO_DIR_MASK.

12d614d0b8 drivers: gpio: add support for Altera Nios-II PIO controller 
The PIO cores on Altera Nios-II processors can be used
for GPIOs and each PIO core can be configured as Input only,
Output only or as Bidirectional port from the Qsys tool.

The present Nios-II softcpu image on the Zephyr only has the
support for Output only port and the PIOs[0:3] are wired to
LED[0:3] on the Altera MAX10 board.
