GPT disk partition with max available number (ex: /dev/mmcblk128) can't
be read/write from U-Boot using read/write command. Here is an example:
=> mmc part
Partition Map for mmc device 0 -- Partition Type: EFI

=> read mmc 0#fip ${loadaddr} 0 4
Could not find "fip" partition
** Bad device specification mmc 0#fip **
** Bad device specification mmc 0#fip **
Couldn't find partition mmc 0#fip
The error is caused by invalid boundary checks. This patch fixes an
issue.
Fixes: 43fd4bcefd4e ("disk: part: implement generic function
part_get_info_by_uuid()")
Fixes: 56670d6fb83f ("disk: part: use common api to lookup part driver")
