uuid: add selection by string for known partition type GUID

Browse Source 
short strings can be used in type parameter of gpt command
to replace the guid string for the types known by u-boot

      partitions = name=boot,size=0x6bc00,type=data; \
                   name=root,size=0x7538ba00,type=linux;
      gpt write mmc 0 $partitions

and they are also used to display the type of partition
in "part list" command
