arm: imx: hab: Implement hab_rvt_failsafe

Browse Source 
This patch implements the basic callback hooks for
hab_rvt_check_failsafe for BootROM code using the older BootROM address
layout - in my test case the i.MX7. Code based on new BootROM callbacks
will just do nothing and there's definitely a TODO to implement that extra
functionality on the alternative BootROM API.
