gpio: of: initialize local variable passed to the .of_xlate() callback

of_flags is passed down to GPIO chip's xlate function, so ensure this one

- we may end up with various configuration errors like:

    gpio-720 (enable): multiple pull-up, pull-down or pull-disable enabled, invalid configuration
