The IVT gives the absolute address of the CSF. There is no requirement for
the CSF to be located adjacent to the IVT so lets use the address provided
in the IVT header instead of the fixed CSF offset currently in place.

Its worth noting if you use u-boot mkimage and the i.MX CST tool as
described in the NXP documentation you will get an image like

IVT | BINARY | CSF not IVT | CSF | BINARY as the code currently assumes.
The IVT header must correctly describe the location of the CSF or the
BootROM will reject it - so the current dependence on a fixed offset is
nothing except limiting.

Fix it now.
