[PATCH v2] scripts: gen_image_generic: allow FAT fs on kernel partition for non-GPT targets

[Tomasz Maciej Nowak]

From: Tomasz Maciej Nowak <tmn505 at gmail.com>

Some old or proprietary bootloader recognise only FAT file system
variants on storage devices with MBR but unfortunately script ties
format of kernel partition to GPT partition table. So, allow kernel
partition file system to be FAT16 or FAT32 if appropriate type is set
in partition table.
