Current implementation of hab_auth_img command needs ivt_offset to authenticate the image. But ivt header is placed at the end of image date after padding.
This leaves the usage of hab_auth_img command to fixed size or static offset for ivt header. New function "get_image_ivt_offset" is introduced to find the ivt offset during runtime. The case conditional check in this function is same as boot_get_kernel in common/bootm.c
With this variable length image e.g. FIT image with any random size can have IVT at the end and ivt_offset option can be left optional
Can be used as "hab_auth_img $loadaddr $filesize" from u-boot script

I'm seeing that function get_image_ivt_offset() requires a length but we are not using it, there is any reason for that?
length is not required to find the ivt offset in the image. I will remove this.
Thanks, Breno Lima
