[U-Boot] [PATCH v2 2/3] imximage: Specify default IVT offset in IMX image

[Bryan O'Donoghue]

This patch adds BOOTROM_IVT_HDR_OFFSET at 0xC00. The BootROM expects to
find the IVT header at a particular offset in an i.MX image.

Defining the expected offset of the IVT header in the first-stage BootROM
image format is of use of later stage authentication routines where those
routines continue to follow the first-stage authentication layout.

This patch defines the first stage offset with an upcoming set of BSP
patches making use of that offset subsequently.
