Currently, there are multiple definitions of run_shell()
for each board that can be build in "xload" configuration.
Now there is only one function used by all boards.

The functions defined in xload.c are used only when "xload"
configuration used; but it gets compiled unconditionally.
This has been fixed as well.

 Change in v2:
    Fixed the typo in the subject s/iomap/omap/
    ...observed when mail reached my inbox :(

 Only build tested with these commands:
   make distclean ; make omap3530_beagle_defconfig ; make ;
   make distclean ; make omap3530_beagle_xload_defconfig ; make ;
   make distclean ; make panda_xload_defconfig ; make ;
   make distclean ; make panda_defconfig ; make ;
   make distclean ; make pcm049_defconfig ; make ;
   make distclean ; make pcm049_xload_defconfig ; make ;
