Christian Gmeiner 476c2fcd28 bootvx: use program header for loading 
The section header address is a VMA whereas the address found in
the program header is a physical one. With this change it is
possible to load and start a vx7 intel generic based image.

$ readelf -l /tmp/vx7

Elf file type is EXEC (Executable file)
Entry point 0x408000
There are 2 program headers, starting at offset 52

For completeness here are the same information for an old vx5 based image. After
this change it is possible to boot vx5 and vx7 (intel generic) images.
