[U-Boot] [PATCH V2 2/3] FAT: make use of disk_partition_t.part

[Stephen Warren]

From: Stephen Warren <swarren at nvidia.com>

This removes the standalone cur_part_nr variable, opening the way to
replacing fat_register_device() with fat_set_blk_dev().

Note that when get_partition_info() fails and we use the entire disk,
the correct partition number is 0 (whole disk) not 1 (first partition),
so that change is also made here.

An alternative to this (and the previous) patch might be to simply
remove the partition number from the printf(). I don't know how attached
people are to it.
