disk: Return the partition number in part_get_info_by_name()
Similar to what blk_get_device_part_str() does, this patch makes part_get_info_by_name() return the partition number in case of a match. This is useful when the partition number is needed and not just the descriptor. Signed-off-by: Alex Deymo <deymo@google.com> Reviewed-by: Simon Glass <sjg@chromium.org>
