gpio: acpi: Factor out acpi_gpio_to_gpiod_flags() helper

Browse source

The helper function acpi_gpio_to_gpiod_flags() will be used later to configure
pin properly whenever it's requested.

While here, introduce a checking error code returned by gpiod_configure_flags()
and bail out if it's not okay.
