[U-Boot] [PATCH V3 1/4] part: add partition number to disk_partition_t

[Stephen Warren]

From: Stephen Warren <swarren at nvidia.com>

The FAT filesystem code knows which partition ID it is operating on.
Currently, this is passed to fat_register_device() as a parameter.
In order to convert FAT to the more standardized fat_set_blk_dev(), the
information needs to come from somewhere else, and the partition
definition structure is the logical place.

v3: Set info->part in get_device_and_partition() when returning "whole
    disk" partition.
v2: No change.
