arm: imx: hab: Only call ROM once headers are verified

Browse Source 
Previous patches added IVT header verification steps. We shouldn't call
hab_rvt_entry() until we have done the basic header verification steps.

This patch changes the time we make the hab_rvt_entry() call so that it
only takes place if we are happy with the IVT header sanity checks.
