arm: imx: hab: Prefix authenticate_image with imx_hab

Browse Source 
Tidy up the HAB namespace a bit by prefixing external functions with
imx_hab. All external facing functions past this point will be prefixed in
the same way to make the fact we are doing IMX HAB activities clear from
reading the code. authenticate_image() could mean anything
imx_hab_authenticate_image() is on the other hand very explicit.
