  sun4u: ensure kernel_top is always initialised

Valgrind reports that when loading a non-ELF kernel, kernel_top may be used
uninitialised when checking for an initrd.

Since there are no known non-ELF kernels for SPARC64 then we can simply
initialise kernel_top to 0 and then skip the initrd load process if it hasn't
been set by load_elf().

  Log Message:

  sun4m: don't use legacy fw_cfg_init_mem() function

Instead initialise the device via qdev to allow us to set device properties
directly as required.
