Merge patch series "part: fix partition searching"

Browse Source 
Mikhail Kshevetskiy <mikhail.kshevetskiy@iopsys.eu> says:

It was noted that a GPT partition with the maximum available partition
number (ex: /dev/mmcblk128) can't be read/write from U-Boot using
read/write commands. Futher investigation shows that the problem is
deeper.

This set of patches fixes uncovered issues.
