arm: imx: add HAB authentication of image to SPL boot
When using HAB as secure boot mechanism on Wandboard, the chain of
trust breaks immediately after the SPL. As this is not checking
the authenticity of the loaded image before jumping to it.
The HAB status output will not be implemented in SPL as it adds
a lot of strings that are only required in debug cases. With those
it exceeds the maximum size of the available OCRAM (69 KiB).
The SPL MISC driver support must be enabled, so that the driver can use OTP fuse
to check if HAB is enabled.
