If the STM32H7 fails to program or erase a full chunk of 256 bytes, the
ECC check will trigger a busfault when trying to read from it.
To speed up erasing and optimize wear, we read before erasing to check
if it actually needs erasing. That's when a busfault happens and the
erase time outs.
The workaround is to add an option to do a full erase without check.

And the protocol option added to the bootloader is the same as for
ArduPilot, so compatible.

- move systick.c under chip specific sources
- move do_jump into chip specific main.c as arch_do_jump
- wrap flash writes to "arch_flash_write" and implement in chip specific main.c
- add bootloader TOC check
- sync image_toc.h with the version currently in use with old bootloader
