stm32f2x: Fix byte order bug.
Do not use buf_set_u32 on integers; they're not buffers.
If using buf_set_u32 on integers, bytes will be exchanged on Big Endian targets.
In this particular case, FLASH_OPTCR was incorrectly written, causing it to often
contain one of these values: 0x00aaaae1, 0x00aaffef, 0x00ffabe1 or 0x00abffe1.
This write-protected the device before flash-programming, causing this command...
flash write_image erase unlock myfile.elf
... to fail, complaining about write-protection.
Repeating the above command would change the OPTCR register each time.
After applying this patch, the OPTCR remains "unchanged".
