Hi Simon,

Convert main_loop() over to use autoconf, and add a required prototype to common.h.
The do_mdm_init variable is now always defined, but this seems like an acceptable compromise.
In fdt_support.h the #ifdef used is CONFIG_OF_LIBFDT. However, even if this is not defined we want to make the functions available for our conditional-compilation scheme. The only place where we really don't have access to these support functions is when USE_HOSTCC is defined. So change the #ifdef to that.

Why not just remove do_mdm_init and use gd->do_mdm_init here?
