Fix vector table bug when using bootloader on ST

The address of the vector table is hardcoded to the start of flash in
many, if not all, ST targets. This causes a crash in applications that
are using a bootloader.  This patch updates the boards STM32F429xI,
STM32F439xI and Odin so they properly handle updating the VTOR with
a bootloader.
