6039e0edc8 imx: hab: Simplify the mechanism 
The current mechanism is unnecessarily complex. Simplify the whole mechanism
such that the entire fitImage is signed, IVT is placed at the end, followed
by CSF, and this entire bundle is also authenticated. This makes the signing
scripting far simpler.

984639039f Rename CONFIG_SYS_TEXT_BASE to CONFIG_TEXT_BASE 
The current name is inconsistent with SPL which uses CONFIG_SPL_TEXT_BASE
and this makes it imposible to use CONFIG_VAL().

Rename it to resolve this problem.
