Subject: [PATCH] [CMAKE] Override .hex start address with 0x08000000

The configurator does rely on the .hex start address being set to
0x08000000. I'm not sure this is actually required and we should
fix the configurator instead. However, in order to allow older
versions of configurator to flash newer firmwares, we should
the .hex files built with cmake compatible for at least some
releases.
