The HABv4 functions need access a part of the ROM which is located in the zero page. This must be done early, before the MMU has been configured and the zero page has been set to faulting. The HAB functions currently use cpu_is_imxxy(). At the stage where HAB is called the i.MX CPU type variable is not yet initialized, so this code only works when only one i.MX type is enabled and cpu_is_imxxy() are compile time constants. To fix HAB support when more than one i.MX type is enabled make the HAB status function SoC specific so that we can drop the use of cpu_is_imxxy().
