I'll answer that myself, since I just found the solution to my problem after
searching for hours.

Turns out the EFI partition needs to be created with --metadata=1.0 instead of
--metadata=1.0:

# mdadm --create /dev/md/EFI --level=1 --raid-devices=2 \
  --metadata=1.0 /dev/sda1 /dev/sdb1

Boots fine now.

Cheers,

Niki
