tools: dynamically allocate imx_header in imximage
Change to dynamically allocate the imx_header to correctly
allocate the IVT, Boot Data and DCD at correct locations
depending on the boot media.
Also check that the Image Vector Table Offset + IVT +
Boot Data + DCD <= Initial Load Region Size.
Previously struct imx_header was always 4096 bytes and was
not dealing correctly with the Image Vector Table Offset.
Now, the memory allocation looks for e.g. SD boot like this
