The macro for_each_set_bit() effectively looks up to the next set bit in array
of bits.
Instead of open coding that switch to for_each_set_bit() in
gpio_chip_set_multiple().
While here, make gpio_chip_set_multiple() non-destructive against its
parameters. We are safe since all callers, i.e.
gpiod_set_array_value_complex(), handle that already.

It seems the code had been changed, but description left untouched.
Update description of the struct acpi_gpio_info and relative comments
accordingly.

Make fwnode_get_named_gpiod() consistent with the rest of gpiod_get() like API,
i.e. configure GPIO pin immediately after request.
Besides obvious clean up it will help to configure pins based on firmware
provided resources.

Please call this 'dflags' as it is called elsewhere as well.
Otherwise looks reasonable to me.
