When eMMC was formattaed for Linux partition table, "userdata" partition is missing. In this case, part_get_info_by_name() iterates over all registered drivers (which are PART_TYPE_EFI, PART_TYPE_DOS and PART_TYPE_ISO). And when it comes to PART_TYPE_ISO (which has empty partition table), we can see next warning in U-Boot output:
** First descriptor is NOT a primary desc on 1:1 **
This patch switches to part_get_info_by_name_type() API in order to check only EFI partitions for "userdata" partitions. This eliminates mentioned warning.
