imx: hab: Check if IVT header is HABv4

The HABv4 implementation in ROM checks if HAB major version
in IVT header is 4.x.

The current implementation in hab.c code is only validating
HAB v4.0 and HAB v4.1 and may be incompatible with newer
HABv4 versions.

Modify verify_ivt_header() function to align with HABv4
implementation in ROM code.
