[U-Boot] [PATCH RESEND] imx-common: hab: fix return value from hab_auth_img

[Eric Nelson]

The authenticate_image routine returns a boolean to indicate
a valid (1) or invalid (0) image.

The hab_auth_img should return CMD_RET_SUCCESS to indicate
success (a valid image), but currently doesn't.

Before this patch, a valid image at addres 0x12000000
with an IVT offset of 0x7a8000 will produce the following:

	=> if hab_auth_img 0x12000000 0x7a8000 ; then
	>     echo worked
	>   else
	>     echo failed
	>   fi
	Authenticate image from DDR location 0x12000000...
	Secure boot enabled
	HAB Configuration: 0xcc, HAB State: 0x99
	failed
