Subject: [PATCH] arm: imx: hab: Implement hab_rvt_check_target

This patch implements the basic callback hooks for hab_rvt_check_target()
for BootROM code using the older BootROM address layout - in my test case
the i.MX7. Code based on new BootROM callbacks will just have HAB_SUCCESS
as a result code. Adding support for the new BootROM callbacks is a TODO.
