Hi,

I hesitated calling this a RFC as I'm not sure everyone will like the
idea.

Basically the issue encountered was the following:
- Device with its storage flashed with a MBR partition table
- Run fastboot to flash a new OS (and new partition table)
- After flashing a GPT partition table, U-Boot couldn't find any of the
  partition names from the GPT
  -> reason is that the partition table entries aren't updated
  -> so U-Boot still believes it's a MBR table inside and so its parsing
  fails

This commit adds an update of the table entries inside the
write_mbr_and_gpt_partitions() function. At first I thought maybe this
should be added in fastboot file (fb_mmc.c) but couldn't think of a good
reason why this shouldn't happened in part_efi directly.

Let me know if you have any questions.

Regards,
Gary
