[flash_ctrl] Remove oob handling altogether The current oob handling is not complete. It only handles an upper bound check but does not check the lower bound. This means the original issue that caused this error can still happen as long as someone supplies a lower address (such as 0x0). After talking it through with the @a-will, the utility of this feature just seems very minor. It also complicates things by pulling a system address map into a peripheral, which really does not seem like the right way to go about this. As a result, I have removed this feature altogether, and will instead rely on software to make sure the addresses being fed to flash_ctrl are within bounds.
