Bryan O'Donoghue c5800b2541 arm: imx: hab: Fix authenticate_image input parameters
u-boot command "hab_auth_img" tells a user that it takes

- addr - image hex address
- offset - hex offset of IVT in the image

but in fact the callback hab_auth_img makes to authenticate_image treats
the second 'offset' parameter as an image length.

Furthermore existing code requires the IVT header to be appended to the end
of the image which is not actually a requirement of HABv4.

This patch fixes this situation by

1: Adding a new parameter to hab_auth_img
   - addr   : image hex address
   - length : total length of the image
   - offset : offset of IVT from addr

2: Updates the existing call into authenticate_image() in
   arch/arm/mach-imx/spl.c:jump_to_image_no_args() to pass
   addr, length and IVT offset respectively.

This allows then hab_auth_img to actually operate the way it was specified
in the help text and should still allow existing code to work.

It has the added advantage that the IVT header doesn't have to be appended
to an image given to HAB - it can be prepended for example.

Note prepending the IVT is what u-boot will do when making an IVT for the
BootROM. It should be possible for u-boot properly authenticate images
made by mkimage via HAB.

This patch is the first step in making that happen subsequent patches will
focus on removing hard-coded offsets to the IVT, which again is not
mandated to live at the end of a .imx image.
