gpio: mmio: add BGPIOF_NO_INPUT flag for GPO gpiochip
When using bgpio_init with a gpiochip acting as a GPO (output only), the
gpiochip ops `direction_input` was set to `bgpio_simple_dir_in` by
default but we have no input ability.
Adding this flag allows to set a valid ops for the `direction_output`
ops without setting a valid ops for `direction_input` by default.
