The EFI spec states that the ESP can be any of FAT12/16/32 but for compatibility doesn't necssarily require the partition to be the EFI partition table ID of 0xef. A number of arm devices will not find their firmware on a FAT partition with an ID of 0xef so also allow the original FAT12/16/32 partition IDs as they are also permissable for an ESP.

v2:
- Add 0x0c option
- Make hex constants consistent
- Move from if to switch statement
Erh...

The 0x80 check was for a different struct member and there are missing break statements. And I suppose the suggestion to use a switch was to bunch up the EFI partition type cases.
ENOCOFFEE?
It was worse, no coffee and an early start for a flight.... OOPS!
