Currently, if atf env is set in the secure board. secure boot
sequence gets bypassed. This is not an expected behaviour. So,
removed support the atf env variable. Instead atf enabled status
can be verified using get_secure_state scm call.
Moreover, as per current design get_secure_state scm call will
not be implemented in ATF in future as well. If its implemented,
Bit 7 should be made to 1.
