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".

- Get partition info from device number and partition name.
- Parse a device number and partition name string in the form of
- "device_num#partition_name", for example "0#misc". If the partition

- of the partition with the given partition_name.
- @param[in] dev_iface Device interface
- @param[in] dev_part_str Input string argument, like "0#misc"
- @param[out] dev_desc Place to store the device description pointer
- @param[out] part_info Place to store the partition information
- @return 0 on success, or -1 on error
Can you please return an error like -EINVAL? -1 is defined as -EPERM whcih seems wrong.
