gpio/microblaze: Eliminate duplication of of_get_named_gpio_flags()
of_reset_gpio_handle() is largely a cut-and-paste copy of of_get_named_gpio_flags(). There really isn't any reason for the split, so this patch deletes the duplicate function Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Cc: Michal Simek <monstr@monstr.eu>
