FDT: only call boot_get_fdt from generic code
All arches except nios2 and microblaze call boot_get_fdt from bootm_start in common/cmd_bootm.c. Having nios2 and microblaze do so as well removes code from their respective do_bootm_linux routines and allows removal of a nasty ifdef from bootm_start. In the case where boot_get_fdt returns an error bootm_start returns and the platform specific do_bootm_linux routines will never get called. Also only check argv[3] for an fdt addr if argc > 3 first. This is already the case for nios2.
