change the get_medium_size() function from
- long (*get_medium_size)(struct dfu_entity *dfu);
+ int (*get_medium_size)(struct dfu_entity *dfu, u64 *size);
so it can return bigger medium sizes than 2GiB, and the return
value is seperate from the size.

I just have a DDP nand with a size of 4GiB, and the
mtd partition layout is:
device nand2 <omap2-nand.0>, # parts = 9
#: name size offset mask_flags
0: spl 0x00080000 0x00000000 0
1: spl.backup1 0x00080000 0x00080000 0
2: spl.backup2 0x00080000 0x00100000 0
3: spl.backup3 0x00080000 0x00180000 0
4: u-boot 0x00780000 0x00200000 0
5: u-boot.env0 0x00200000 0x00980000 0
6: u-boot.env1 0x00200000 0x00b80000 0
7: mtdoops 0x00200000 0x00d80000 0
8: rootfs 0xff080000 0x00f80000 0
so the last partition is to big for returning the size in a long.
