MA-16954 set partition type to efi after flash gpt partition

If the target device have DOS partition, uboot will save the partition
type as dos partition at early stage when the driver bind the device.
After the gpt partition is flashed, uboot will try to reload the DOS
partition, instead of the the EFI partition.

In this commit, if the GPT partition is successfully flashed, set the
partition type to be PART_TYPE_EFI if necessary, so the EFI partitions
will be reloaded.
