disk: part: Extend API to get partition info
This patch adds part_get_info_by_dev_and_name_or_num() function which
allows us to get partition info from its number or name. Partition of
interest is specified by string like "device_num:partition_number" or
"device_num#partition_name".
The patch was extracted from [1].
