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

While at it also remove the unused #define HEADER_OFFSET.
