Use firmware configuration instead of NVRAM (initial patch by Aurelien Jarno)

Use firmware configuration device for boot device, kernel, initrd and kernel command line parameters on PPC, Sparc32 and Sparc64. Update OpenBIOS images to r479 which supports the change. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6777 c046a42c-6fe2-441c-8c8c-71466251a162
