Theese devices do not have a gap in sector numbering.
The driver translates sectors numbers 12 13... to 16 17... as used on dual
bank flash devices. Therefore erase of sector 12 and above fails with error
'stm32x device protected'
on F413/423.
Drop sector number translation for devices without has_large_mem flag.
